What is the difference between Rust Bullet Standard (Gold Label) and Rust Bullet Automotive (Silver Label)?

Both the Standard and Automotive formulations have the same patented anti-corrosive properties and will outperform any other rust inhibitive, protective coating on the market. The Automotive formula is formulated to easily flow through an HVLP automotive spray system, and will produce a smoother finish typically needed for automotive projects.

What is Rust Bullet’s product line?

Rust Bullet Standard and Automotive are Super-Tough, High-Performance, Industrial Grade Coatings that can be applied on new, clean metal or directly over surface rust, providing permanent corrosion protection with phenomenal adhesion. Rust Bullet has been awarded an Unprecedented Two U.S. Patents by the United States Patent and Trademark Office. Rust Bullet Automotive is to be used for Automotive applications whereas the Standard is for Commercial, Industrial, Home and Farm, and Marine Applications.

Rust Bullet for Concrete is an industrial strength protective polyurethane coating specially formulated for concrete. This special formulation not only improves the appearance of concrete, it provides an impervious shield allowing easy clean-up of oil, grease and chemical spills along with strong protection against impacts, abrasives, and atmospheric elements. Use for all your concrete flooring needs including garage floors, walkways, paths and much more.

Clear Coat for Concrete is an industrial strength, clear, anti-skid coating formulated as a top coat for the Rust Bullet for Concrete Coating. This special formulation is used to create a beautiful, safe, anti-skid, glossy finish. Can also be used to seal in decorative chips or flakes.

BlackShell, WhiteShell, ColorShell, and Clear Shot are formulated specifically as top coats for the Rust Bullet Standard, Automotive and Concrete Formulations. They all cure to a beautiful gloss finish and are scratch and chip resistant, and UV resistant. They also offer unbeatable chemical resistance. The ColorShell's are ANSI Z535 Compliant OSHA Safety Colors. ColorShell's are available in Red, Orange, Yellow, Green, Blue and Purple.

Rapid Fire Accelerator is designed for spray applications of Standard, Automotive, and Rust Bullet Top coats. Rapid Fire decreases the drying time needed between coats, ultimately reducing project completion times up to 80% while maintaining optimal coating performance.

Metal Blast is a metal surface cleaner and conditioner that is like having three products in one. It dissolves rust, degreases and it etches metal. Metal Blast eliminates the high cost of extensive surface preparations by properly etching surfaces with minimal or poor adhesive qualities providing an ideal anchor pattern for a superior coating bond. It works on any metal surface including aluminum, stainless steel and shiny polished metal resulting in optimum coating performance.

Bloxygen blocks Oxygen, protects and preserves opened Rust Bullet Coatings during storage. Bloxygen uses ultra-pure Argon, an inert gas, to drive the oxygen out of partially used containers of Rust Bullet Coatings and preserve the coating for up to six months. A short spray into the container will protect the Rust Bullet from reacting with the oxygen or moisture present in our normal atmosphere.

Solvent is for cleanup, equipment prep, and the thinning of Rust Bullet Coatings. Effectively clean equipment such as paint pots, lines, guns, brushes and rollers, as well as spills, drips and over spray from coatings applications. Use to thoroughly flush and clean spray equipment before, after and between coats to avoid possible damage to spray equipment. Do not thin unless directed by Rust Bullet Technical Support. The approximate thinning ratio is 3% to 5% by volume (i.e. 1 to 1.5 oz. solvent per quart of coating).

Metal Jacket is a non-greasy, non-dirt collecting, non-tacky, dust retardant, continuous, flexible, removable film that will not crack, peel, or flake. Metal Jacket protects all metals against atmospheric rust and corrosion, salt spray, high humidity, chemical fumes, abrasive matter, fingerprinting and fingerprint corrosion. Translucent coating allows for easy reading of identification markings stamped on parts.

Safety Guidelines

The Rust Bullet Products SDS documents contain all safety recommendations for preparation, application and clean up, and can be found through the following link:

Rust Bullet Products SDS Sheets
A certain degree of risk is involved in the use, or more properly, the misuse, of most industrial materials; Rust Bullet is no exception to this rule. Ensure adequate ventilation and fresh air when working with Rust Bullet coatings. Use a NIOSH-approved Half-Mask Organic Vapor Respirator and a P100 filter attached with a filter cover. Filters must be changed if and when they become saturated. Wear protective clothing, gloves, and eye protection during set up, application, and clean up.

It is critical to avoid any conditions that may cause a fire. Avoid open flames, pilot lights, sparks, heating elements, cigarettes, or any and all possible sources of ignition.

Important points for a successful project

  • Rust Bullet coatings are ready to use right from the can. Thinning is not necessary. Adjust the application equipment as opposed to adjusting the coating.
  • Rust Bullet Coatings should be stirred thoroughly by hand for at least 3 minutes. Do not shake the can to mix. Avoid creating air bubbles in the coating during mixing.
  • Only pour out what you intend to use in one hour and quickly re-seal the can. Wipe clean any coating from the rim of the container before resealing.
  • Use Bloxygen to keep any left over from curing up to six months. Bloxygen is an inert Argon gas that will displace the oxygen and provide a much longer storage life for unused portions of previously opened containers.
  • Rust Bullet Solvent works best for cleanup, equipment prep. Do not use lacquer thinner, vinyl thinner, epoxy solvent, or any alcohol or unapproved solvent. If Rust Bullet Solvent is unavailable, Xylene, Toluene, or Acetone may be substituted.
  • When using spray equipment, flush Rust Bullet Solvent through pumps, lines and guns prior to spraying to remove any existing moisture or other contaminates.
  • Never allow sweat, rain, mist or other contaminates to fall into a Rust Bullet Coating. Even a drop or two can drastically affect results.
  • Apply in thin, even coats. Thick coats will cause bubbling , also known as Solvent Popping, and eventually a coating failure.
  • Standard, Automotive and Rust Bullet for Concrete do not require a top coat, however, if you want a different color, a top coat may be applied between 2-6 hours, up to 12 hours after the final coat. If 12 or more hours have lapsed, wait for the last coat to cure for at least 24 hours, then lightly scuff with 150 grit; enough to break the glaze to create a surface profile.
  • Rust Bullet BlackShell, WhiteShell, Clear Shot, and Color Shells are top coats and are meant to be used as the final coats. You may use them as a stand alone coating, however, you will not receive the longevity of using them as a top coat over the Standard, Automotive, or Concrete Formulations.

What is the recommended surface preparation for Rust Bullet Coatings?

The surface to be coated must be completely dry and must be free of loose rust, paint, moisture, dirt, mildew, oily substances, wax and loose particles, or any other surface contaminates such as embedded chlorides etc. Remove any loose rust, loose paint, or loose mill scale by lightly scraping, sanding, media blasting or wire brushing. If necessary, we recommend cleaning the surface with Rust Bullet Metal Blast. No additional surface preparation should be necessary. If there is existing paint on the surface, lightly scuff the surface to create a profile for adhesion. Rust Bullet works best when in direct contact with the rusted surface or bare metal, so previous paint should be removed as much as possible. Refer to the Application Guidelines for more information.

Should I apply Rust Bullet only where rust is apparent?

If it is made of iron or steel, it will rust and corrode if left unprotected. Rust Bullet should be applied even where rust is not apparent to prevent the occurrence of future corrosion. It not only kills existing rust, it seals and protects surfaces that have not yet started to rust, providing years of prevention.

Why do I need to apply multiple coats of Rust Bullet?

As Rust Bullet cures, it expels solvents and releases a carbon dioxide gas while dehydrating the rust. The first coat of Rust Bullet soaks through the rust down to the metal below, encapsulates the rust and dehydrates it. As the first coat dries and gases off, tiny pin holes may form in the coating. The second coat is critical to fill any pin holes and seal the surface with an air-tight, armor-like shield of protection. If the pin holes are not sealed after the first coat, air and moisture may penetrate the coating exposing the surface to further damage. Apply additional coats to achieve the desired dft for the appropriate protection for the project.

Can Rust Bullet be applied on damp or wet surfaces?

Rust Bullet is moisture sensitive. It is extremely important that the surface to be coated is completely dry to allow proper curing and adhesion. Extreme care should be taken to ensure all coating projects are completely dry.

Product Preparation – Stirring & Mixing

  • Do not open and stir a Rust Bullet Coating when the temperature is below the dew point.
  • Rust Bullet Coatings should be stirred thoroughly for at least 3 minutes or until completely uniform and homogenous (avoid whipping air into product). Shaking the container prior to application may cause the formation of bubbles in the finish of the coating. Never stir the product by mechanical means; this will trap air molecules containing moisture between the coating and the surface causing improper curing and possible coating failure.
  • Rust Bullet Products that have been sitting for six months or longer may develop settling. Follow the same stirring instructions, but increase the stir time and be sure to break up any clumps on the bottom of the container, if any.

What can be used to thin Rust Bullet?

The exact balance of viscosity, solvent, and active ingredients must be maintained; therefore, Rust Bullet Coatings must only be thinned with Rust Bullet Solvent. Thinning or adding any other product to a Rust Bullet Coating will compromise the performance and quality of the finished product. Use Rust Bullet Solvent for thinning at an approximate ratio of 3% - 5% by volume (i.e. 1.0 to 1.5 oz solvent per quart of coating.

Can I pour Rust Bullet into another container?

Yes. If, for any reason, Rust Bullet is transferred to another container; clean, unlined, metal paint cans (or similar unlined metal containers) must be used. Make sure that the container can be properly sealed. Stir the contents for at least three minutes before transferring any portion of product to a different container. During application, pour out the portion you will use in approximately one hour and reseal the lid as soon as possible. Use BlOxygen to displace the oxygen with an inert gas (Argon), to prevent curing of previous opened containers of Rust Bullet Coating.

Can a surface coated with Rust Bullet be welded?

No. The extreme heat involved in the welding process will disintegrate Rust Bullet, and most other coatings. If welding is necessary after Rust Bullet has already been applied, then it should be removed prior to welding, and reapplied afterward.

What is the temperature service range of Rust Bullet Coatings?

After curing, all Rust Bullet coatings have a service temperature range of 314°F (157°C) continuous, and can tolerate maximum temperatures between 617°- 662°F (325°-350°C) for up to 72 hour periods.

What should I do if I waited too long before applying the next coat of Rust Bullet?

Drying time between coats of Rust Bullet is approximately 2 to 6 hours. If 12 or more hours have lapsed, wait for Rust Bullet to harden for at least 24 hours then lightly scuff with 150 grit; enough to break the glaze to create a surface profile.

How can Rust Bullet Coatings be applied?

Brush – Regular bristle brushes. Do not use foam! Use cheaper type of brushes, as you will need to discard of the brush when finished. A brush application achieves approx. 1.5 to 2 mils per coat.

Roller – Use a 3/8 inch nap roller. Do not use a foam roller. A roll application achieves approx. 1.5 to 2 mils per coat.

Note: Rust Bullet for Concrete can be sprayed with an Airless sprayer, and applied by brush or a roller. Clear Coat for Concrete cannot be sprayed. It is applied by brush or roller only.

Spray Equipment:

Airless: The Rust Bullet Standard and Rust Bullet for Concrete can be applied using airless spray equipment. A 517 to 523 tip at an approximate 2000 - 3000 psi is recommended and will give you about 3-4 mils per coat.

HVLP: The Rust Bullet Automotive may be applied with HVLP (High Volume, Low Pressure) spray equipment. Use a primer size tip, dependent upon the equipment and the psi this may range from a 1.7 to 2.0 tip at 40-60 psi. An HVLP application gives about 2-3 mils per coat.

Tips for a successful spray application:

  • Rust Bullet Coatings are ready to use right from the can; thinning is not necessary, do not thin.
  • Prior to spraying, run Rust Bullet Solvent through the spray equipment to remove any moisture that is trapped in the sprayer.
  • After each coat of Rust Bullet is applied, flush the gun or submerge the tip in Rust Bullet Solvent.
  • Application equipment and filters must be cleaned after use to avoid damage to the sprayer.
  • Any remaining Rust Bullet Coating will cure and likely destroy the equipment.
  • When the spray gun is not in use, such as between coats, it should be completely submerged in a container of solvent.
  • Straining through a nylon bag strainer is recommended.
  • Follow Stirring Instructions thoroughly before application.
  • Inspect all spray equipment and ensure it is clean and in good working order prior to application.
  • Flush Rust Bullet Solvent through pump, line and gun to remove any existing moisture or alcohol from previous coatings or solvents.
  • Do not re-circulate the Rust Bullet Solvent through the pump, as the Solvent will be contaminated with moisture and debris.
  • Overspray is unavoidable with a spray application, however, most sprayers now have adjustable pressure control to spray a wider range of materials with more control and reduced overspray.
  • Overspray is controlled by the operator and the choices made, such as tip size, tip condition, pressure, distance, angle of spray gun in relation to surface, wind, etc.
  • Any sprayer will produce some form of overspray, but there are two main ways to help reduce the overspray; a) set your pressure control at the lowest possible pressure, while still maintaining a solid fan pattern; b) ensure that the correct tip size is being used. Using a tip that is too large, will only result in excess paint being applied to the surface.
  • Ensure that minimum cure times are followed before the application of a subsequent coat.

NOTE: If Rust Bullet Solvent is unavailable, xylene, toluene or acetone may be substituted.

What steps are required when applying a top coat over Rust Bullet?

A top coat should be applied from the time the Rust Bullet Coating is dry to the touch, up to 6 hours after the final coat of Rust Bullet. If 6 or more hours have lapsed, wait for Rust Bullet to harden for at least 24 hours then lightly scuff with 150 grit; enough to break the glaze to create a surface profile.
If a spray application of Rust Bullet has been accelerated by adding Rust Bullet Rapid Fire Accelerator, a top coat may be applied approximately one hour after the final coat of the accelerated Rust Bullet coating has been applied.
If you are using a premium finishing paint and the manufacturer has specific primer requirements, it is recommended you apply the primer over Rust Bullet after the surface has been scuffed.

Why do I need to apply at least two coats of Rust Bullet?

Rust Bullet releases carbon dioxide gas during the curing process. This “gassing off” process may create small pin holes in the first coat of Rust Bullet. The second or third coat seals these tiny pin holes, forming an air tight armor tuff seal that protects the surface. If the pin holes are not sealed, air and moisture may penetrate Rust Bullet, allowing rust and corrosion to form. Rust Bullet is a simple to apply, low maintenance, super tough, high performance rust inhibitive coating. The first coat of Rust Bullet penetrates and dehydrates the rust down to the original metal surface. The second coat of Rust Bullet is necessary and critical to fill any pin holes in the first coat and ultimately forms an armor like shield on the surface. A two to three coat application typically achieves a dft (dry film thickness) of the required 6 mils for general applications. Additional coats may be necessary to achieve the appropriate dft for your project.

How can I tell when to apply the next coat of Rust Bullet?

When applying additional coats of Rust Bullet or BlackShell the previous coat should not be wet or tacky; if you are unable to transfer the coating to a gloved finger, the surface is ready for an additional coat. Approximate drying time between coats is two (2) to four (4) hours for Rust Bullet Coatings, depending on humidity levels. When excessive wet film is applied, additional cure time will be necessary. Rust Bullet Coatings are moisture sensitive; in high humid conditions of 80%+, Rust Bullet will cure much faster than it will in lower humidity. When applying additional coats from one day to the next, especially in the morning, make sure there is no dew or condensation on the previous coat. The surface to be coated must be completely dry.

Rust Bullet Rapid Fire Accelerator can be added to the Rust Bullet coating formulas to decrease the normal recoat time of 2 to 4 hrs to approximately 30 to 40 minutes per coat. Rapid Fire makes it possible to apply multiple coats of Rust Bullet in a single day and reduces project completion time by as much as 80%. A Rust Bullet coating accelerated with Rapid Fire can be applied with either an HVLP Spray System or an Airless Spray System. For maximum rust prevention, ensure that corners, edges, and heavily pitted areas are adequately covered. Apply an adequate number of coats sufficient to achieve the dry film thickness appropriate for the project.

What do I do if I waited too long to apply my next coat of Rust Bullet?

If an additional coat of Rust Bullet is needed and more than 24 hours have passed, the coated surface should be etched with Rust Bullet Metal Blast or scuffed up with 150 grit sandpaper to reopen Rust Bullet’s pores. This will allow proper adhesion of an additional coat. This 24 hour period is decreased in areas with higher humidity levels.

Why do I have bleed through?

You should not have rust coming to the surface unless Rust Bullet was improperly applied. Wipe down the coated surface with Rust Bullet Solvent and inspect the surface to rule out the possibility that the rust stains are caused by rusty water or fluid that has dripped onto the surface coated with Rust Bullet from another area that was not coated. If another application of Rust Bullet is necessary due to an inadequate initial application, etch the existing coating with Rust Bullet Metal Blast or scuff up the surface with 100 to 150 grit sandpaper and apply an additional two coats of Rust Bullet or Rust Bullet Automotive. Remember, surfaces to be coated must be completely dry.

How do fuels affect Rust Bullet?

Fossil fuels, such as refined oils (gasoline, diesel, jet fuels and kerosene) will not affect the integrity of the cured Rust Bullet Coating. Additionally, renewable fuels such as Bio-diesel and Ethanol will have no adverse effect on substrates coated with Rust Bullet.

What causes bubbling in the finish of a project coated with Rust Bullet?

Some of the most common reasons for bubbling are:

  • Applying Rust Bullet too thick. As Rust Bullet cures, small gas bubbles can get trapped in overly thick areas of the coating, creating bubbles in the finish, called Solvent Popping. When using a brush or roller, Rust Bullet should be applied evenly without buildup in a crosshatch method (an up and down, side to side continuous motion).
  • Prematurely applying a subsequent coat over a partially wet previous coat will trap the escaping gas during the curing process causing bubbles in the finished coating.
  • Shaking the can creates air bubbles in the product. Prior to application, Rust Bullet must be stirred thoroughly until completely uniform and homogeneous (approximately 3 minutes). Shaking the container may cause the formation of bubbles in the finish of the coating.
  • Using a Mechanical tool to stir or mix the coating will cause a vortex, drawing air into the product. Avoid whipping air into product as the same results will occur as noted above.

Can Rust Bullet be applied over existing paint?

When you have an existing coating that exhibits poor adhesion and is flaking off any coating applied over that coating is subject to the same behavior. As this coating continues to lose its bond with the substrate, the Rust Bullet or any coating on top would pull up with it or bubble. You can scuff up the surface and apply several coats of Rust Bullet, and extend the life. Although it will provide protection and longevity, it will not have the optimum performance of an application over a surface that does not have an existing coating failure. To achieve maximum adhesion and performance, it is always recommended to remove any old paint or coating before applying Rust Bullet.

How do I remove Rust Bullet from skin?

Take precautions to avoid contact of Rust Bullet Products with eyes, skin, clothing, or other objects not intended to coat. Wear the most appropriate protective clothing, gloves, and eye protection during set up, application, and clean up. If Rust Bullet coatings comes in contact with skin, immediately wash with soap and water for at least 5 minutes. Rust Bullet that has dried on the skin will wear off in approximately seven to ten days. Refer to the Rust Bullet MSDS Section 4 First Aid Measures for additional information.

What are the proper equipment clean-up procedures?

  • The Rust Bullet Application Guidelines contain complete detailed clean-up information. Application equipment must be cleaned immediately after use to avoid damage. Spills must be cleaned up immediately with Rust Bullet Solvent or the product will harden and become next to impossible to remove. Avoid getting on body, clothes, or any surface not intended to be coated. Rust Bullet Coatings are permanent; after curing, Rust Bullet can only be removed with rigorous abrasive action. Clean up fresh, uncured Rust Bullet immediately by using Rust Bullet Solvent, following the directions on the label. Washing with soap and water may work, if done immediately.
  • Use Rust Bullet Solvent for Cleanup. Do not make assumptions about other cleanup solvents without consulting Rust Bullet Customer Support. Even a very small contamination of Rust Bullet with alcohol or other hydroxyl-containing solvents can destroy the moisture-cure reaction partly or entirely without any indication or jelling.
  • Spills must be cleaned up with Rust Bullet Solvent immediately or the product will harden and become next to impossible to remove. Avoid getting on body, clothes, or any surface not intended to be coated. Rust Bullet Coatings are permanent; after curing, Rust Bullet can only be removed with rigorous abrasive action. Clean up fresh, uncured Rust Bullet immediately by using Rust Bullet Solvent, following the directions on the container. Washing with soap and water may work, if done immediately.
  • Application equipment must be cleaned with Rust Bullet Solvent immediately after use to avoid damage. Thoroughly flush equipment clean with Rust Bullet Solvent. Do not leave residue as it will harden and become insoluble in solvent. Clean equipment as you would with any typical two component catalyzed coating. Always clean brush or roller thoroughly. Dunking dirty equipment in Rust Bullet Solvent will not prevent the coating from curing overnight.

NOTE: If Rust Bullet Solvent is unavailable, xylene, toluene or acetone may be substituted.

When can I apply a top coat if the Rust Bullet has been accelerated with Rapid Fire?

Wait approximately 1 hour before applying a topcoat over the final coat of Rust Bullet Standard or Rust Bullet Automotive that has been accelerated with Rapid Fire. The previous coat should be tack free.

IMPORTANT: A Rust Bullet coating that has not been accelerated by adding Rapid Fire can be top coated between approximately 2-6 hours after the application of the final coat of Rust Bullet with no additional preparation.

Can Rust Bullet be applied over fiberglass?

There are several issues to consider when painting over fiberglass, especially one that has an existing failing paint. One issue being application of a new coating system over an older, failing coating and one being application on a very delicate and porous surface. You should remove of as much of the older coating as possible to alleviate its continued failure to influence the success of the new coatings. The fiberglass would need to be washed, allowed to dry and then lightly scraped to remove surface paint, wax or other contaminants. A non-chemical method of removal is to lightly scrape as much paint off as possible. If too much pressure is applied, the fiberglass may be damaged. Using a heavy-duty sponge and warm water, coat the scrubbing surface of the sponge with baking soda. Scrub the fiberglass with the baking soda to remove any paint left behind after the scraping. The baking soda will be a bit more labor intensive but will avoid damage that comes with chemical strippers or paint thinner when used on fiberglass. Thin, multiple coats of urethane is the most commonly recommended coating for application on the fiberglass, so Rust Bullet is very suitable for the job. A recommended 12 mil dry film thickness of Rust Bullet Standard Formula should be achieved prior to the application of the desired topcoat. As the fiberglass will tend to be porous and the applied coats thin, you will need more coats of the Rust Bullet than usual to achieve the appropriate film thickness on this project.

What is the proper storage & handling of Rust Bullet Products?

Care should be taken to ensure that previously opened containers or left-over partial containers are kept sealed during storage. Rust Bullet coatings are moisture sensitive; limit the time the container is opened. During application, pour out the portion you will use in approximately one hour and reseal the lid as soon as possible. Immediately wipe clean any Rust Bullet from the rim of the container and reseal. This should be done every time you use Rust Bullet and in between coats. Never pour back into the original container any Rust Bullet coating that has been exposed to the outside air for any length of time because it will destroy the remaining product. The shelf life of Rust Bullet coatings is at least two years for unopened containers and approximately one month for containers that have been opened. Product storage temperature range is 33°F to 120°F. Rust Bullet is a specialized moisture sensitive product; containers that have been opened should be used within in a few months for proper coating performance. Rust Bullet Coatings improperly stored or stored beyond the recommended shelf life, opened or unopened are not eligible for the product return policy as published by Rust Bullet, LLC. You may use Bloxygen to preserve Rust Bullet Coatings up to 6 months. Bloxygen is an inert Argon gas that can be floated over the top of the unused portion of the Rust Bullet Coatings just prior to properly resealing the lid. This will displacing the oxygen and provide a much longer storage life for unused portions of previously opened containers.

Concrete

Which Rust Bullet product do I use for concrete?

Rust Bullet, LLC has introduced a new coating specifically formulated for concrete applications called “Rust Bullet for Concrete”.

What is Rust Bullet for Concrete? Is it a two part epoxy?

No, Rust Bullet for Concrete is not a two part epoxy. There are no messy mixing ratios and is ready to use right from the can. Rust Bullet for Concrete is an industrial strength protective polyurethane coating, specially formulated for concrete applications.

Do I need a non-skid additive? Is Rust Bullet for Concrete slippery after it has dried?

Because tread on shoes are all different, and the possibility of spilling something on a coated floor is inevitable, we do recommend to use a non-skid additive. Make sure the non-skid additive is compatible with a solvent based, moisture cure urethane.

Why Rust Bullet and not Epoxy?

Rust Bullet for Concrete is a one part multiple coat process. This means there is no precise, messy mixing ratios. Rust Bullet is fully cured at around 72 hours after the last coat is applied. Epoxy coatings generally take 7-10 days to fully cure, some even require force curing. Additionally, Rust Bullet can cure at temperatures as low as 32°F, which is advantageous during the winter months. Epoxy coatings require temperatures above 50°F.

What color is Rust Bullet for Concrete?

Metallic Gray; similar to the dull side of aluminum foil

Can I coat all types of concrete surfaces?

Rust Bullet for Concrete is ideal for most concrete surfaces. The concrete substrate must be structurally sound, thoroughly clean and dry. Make sure the substrate is free of loose paint, moisture, dirt, mildew, oily substances, wax, loose particles, and other debris, prior to application. New concrete must be cured at least 30 days.

Can I apply Rust Bullet for Concrete on the concrete around my fireplace?

After curing, all Rust Bullet coatings have a service temperature range of 314°F (157°C) continuous, and can tolerate maximum temperatures between 617°- 662°F (325°-350°C) for up to 72 hour periods.

Can I apply it myself?

Yes. Rust Bullet for concrete is easy to apply and can be used by anyone from DIY consumers to professionals.

Can I apply Rust Bullet to new concrete?

Yes, Rust Bullet for Concrete may be applied to unsealed concrete after the concrete has cured for thirty (30) days.

What do I do if my concrete has been sealed with a concrete sealer?

In most cases, the surface will need to be ground to create a profile for adhesion. This can be done mechanically or by hand.

Does Rust Bullet protect against hot tire pickup? Chemical spills?

Yes, Rust Bullet for Concrete will not break down from hot tire pick up. Rust Bullet for Concrete not only improves the appearance of concrete, it provides an impervious shield allowing easy clean-up of oil, grease, and chemical spills along with strong protection against impact and abrasives.

How much do I need? Is the coverage the same for all coats?

Theoretical coverage is approximately 300-400 ft²/gal/coat depending on the method of application and the porosity. Generally on a concrete surface, the first coat will take the most coating as it seeps into the pores of the concrete. The second and subsequent coats will take less.

How do I prepare my floor?

The concrete substrate must be structurally sound, thoroughly clean and dry. Make sure the substrate is free of loose paint, moisture, dirt, mildew, oily substances, wax, loose particles, and other debris, prior to application.

Do I have to acid etch my floor before applying Rust Bullet for Concrete?

No, acid etching is not required nor is it recommended.

Do I have to apply a concrete sealer prior to applying Rust Bullet for Concrete?

In most cases no. In some cases, when the concrete is extremely porous, it may be advantageous to use a penetrating sealer. A penetrating sealer will fill the pores and prevent extreme absorption of Rust Bullet for Concrete, and will leave a paintable surface.

What can I use to remove oil or grease stains off of my concrete?

Use a mild detergent such as dish soap and water or Simple Green. Do not use any other type of chemical without asking Rust Bullet Technical Support. Not all products are compatible with Rust Bullet for Concrete.

How do I determine if the concrete is dry enough for application?

Rust Bullet for Concrete is moisture sensitive. Even the smallest amount of moisture on the surface will cause a coating failure. One way to test for moisture is to cut a sheet of plastic in a 1’x1’ square and tape the edges onto the floor. Make sure to completely seal the edges so no air can escape. Leave it for 24 hours. Look for condensation on the underside of the plastic sheet or a visible darkening of the slab below the plastic that is damp to the touch. Both are signs of an excessively moist floor. Another way is to use a calcium chloride test kit which are sold at home improvement stores. Follow the kit directions.

How is Rust Bullet for Concrete applied? What is the best method?

Apply by brush, roller or spray equipment. If using a brush, use ones that can be discarded when the project is completed. If using a roller, use a 3/8” nap roller. Do not use foam brushes or foam rollers. If using Spray equipment, use and Airless sprayer with a 517-523 size tip with 3000 – 5000 PSI. The best method depends on the applicator and their experience, and the application equipment. Spray application will give the smoothest most even finish. A roller application is less time consuming than using a brush.

How many coats do I need to apply?

Rust Bullet for Concrete is a minimum two coat application to seal the surface. Additional coats are recommended for high traffic areas and commercial shops. A minimum 9 mil WFT (2-3 coats) is required for residential applications, and a minimum 12 mil WFT (4-5 coats) is required for Commercial/Industrial applications for the warranty to be applicable.

How long do I wait between coats?

Optimum dry time between coats is when the coat is dry to the touch; about 2-4 hours up to 12 hours. The previous coat should not be wet or tacky; if there is no transfer of coating to a gloved finger it is safe to apply an additional coat. After 12 hours, the surface must be lightly scuffed with 150 grit, to break the glaze of the coating. This 12 hour time frame is decreased in higher humidity areas.

What is the ideal temperature range and humidity level to apply Rust Bullet for Concrete?

Ideal application temperature is between 50°F (10°C) and 80°F (27°C) with humidity below 90%. Never apply a Rust Bullet coating while raining or under threat of rain. Do not apply to surfaces when existing temperature of the surface exceeds 190°F (90°C) or is below 32°F (0°C).

What to do if I see roller marks?

When using Rust Bullet as your concrete floor coating, the roller marks generally appear because the thickness of the coating is not even throughout. As you are rolling each section, watch the already coated sections for those roller marks. If they start to appear, take the roller without adding more paint, and with no pressure on the roller handle, roll over the coated surface to even the coats out.

Can I apply Rust Bullet for Concrete over existing paint?

It is recommended to remove as much existing paint as possible. If there are areas that are tightly adhered, etch the painted surface before applying Rust Bullet for Concrete.

Do I have to thin Rust Bullet for concrete?23. Do I have to thin Rust Bullet for concrete?

No, Rust Bullet for Concrete is ready to use right from the can.

How do I use a non-skid additive with Rust Bullet for Concrete?

There are two ways to use a nonskid additive with Rust Bullet for Concrete. One is to mix a non-skid additive into the last coat of Rust Bullet for Concrete (follow the non-skid manufacturer mixing directions), or Sprinkle onto a tacky coat of Rust Bullet for Concrete then apply an additional coat or topcoat to seal.

What if I decide I want a non-slip surface after my coated floor has cured?

The already coated surface will need to be etched with 150 grit, and another coat applied with the non-skid added.

What is the procedure for applying additional coat(s) of Rust Bullet for Concrete after my project has been completed and is dry/cured?

If additional coat(s) of Rust Bullet is needed and more than 24 hours have passed, the coated surface should be scuffed up with at least a 150 grit to reopen Rust Bullet’s pores. Only a light scuff is required to break the glaze of a cured Rust Bullet Coating to allow for adhesion of another coat. This 24 hour period is decreased in areas with higher humidity levels.

If I want a different color other than metallic gray, can I top coat Rust Bullet for Concrete and when should it be applied?

Yes, use the Rust Bullet top coats; BlackShell, WhiteShell, Color Shell’s or Clear Shot for a gloss colored finish. Apply the top coat when the last coat is dry to the touch; about 2-4 hours up to 12 hours. The previous coat should not be wet or tacky; if there is no transfer of coating to a gloved finger it is safe to apply an additional coat. After 12 hours, the surface must be lightly scuffed with 150 grit, to break the glaze of the coating. This 12 hour time frame is decreased in higher humidity areas.

Do I have to apply a top coat? Will Rust Bullet for Concrete yellow or change color over time? Is it UV Resistant?

No, a top coat is not required. Rust Bullet for Concrete is UV, chip, and scratch resistant. Once fully cured, Rust Bullet for Concrete is resistant to chemical and acid spills.

Can I add decorative flakes to my Rust Bullet for Concrete application? What is the process for applying them?

Yes, the addition of decorative flakes should be done when the last coat of Rust Bullet for Concrete is wet. Spread the flakes on a wet coat of Rust Bullet for Concrete, then seal the flakes in with a coat of the Rust Bullet Clear Shot. If a slip resistant surface is desired, a MCU compatible nonskid should be added to Clear Shot. TIP: Flakes should be distributed by two people. One person rolling the coating while the other person distributes the flakes.

Can I apply BlackShell, WhiteShell, or ColorShell on top of flakes?

No, you should not apply BlackShell, WhiteShell, or ColorShell over decorative flakes. You will not be able to see the flakes. Use the Rust Bullet Clear Shot as a last coat to seal the flake.

How long do I have to wait to walk on my freshly coated floor?

Wait a minimum of 8 hours before walking on a coated floor. It is recommended to do a test in a inconspicuous place before walking on it. If another coat is to be applied before this time, spiked shoes are recommended. This time may increase in areas with low humidity.

How long do I wait to drive or put all my stuff back onto my freshly coated floor?

Rust Bullet for Concrete will be fully cured within 3-5 days. Heavy items should not come in contact with your floor before this time.

How do I remove Rust Bullet for Concrete if I spill it on a surface I didn’t intend to coat?

Spills must be cleaned up with Rust Bullet Solvent immediately or Rust Bullet for Concrete will harden and become next to impossible to remove. Rust Bullet Coatings are permanent after curing, Rust Bullet can only be removed with rigorous abrasive action with a mechanical grinder/sander. Clean up fresh, uncured Rust Bullet immediately by using Rust Bullet Solvent, following the directions on the container. If Rust Bullet for Concrete gets on your skin, wash it with soap and water immediately.

Can I apply any Rust Bullet WhiteShell, BlackShell, Clear Shot or ColorShells without using Rust Bullet for Concrete?

Rust Bullet WhiteShell, BlackShell, Clear Shot or ColorShells can be independently applied to your floor for some protection, however, they do not give the same protection or longevity as Rust Bullet for Concrete. Rust Bullet for Concrete is designed to protect your concrete from the elements for several years. The Rust Bullet topcoats are for designed aesthetic purposes to be applied as finish coatings.

Can I use Rust Bullet for Concrete on my metal trim?

Yes, Rust Bullet for Concrete may be used on metal. A minimum 2 coat application, allowing each coat to completely dry prior to the next, is required for corrosion protection.

How do I clean my concrete that has been coated with Rust Bullet for Concrete? What if it is a chemical?

Always check with the manufacturer for proper clean up and disposal of any chemicals. A cured Rust Bullet for Concrete Coating provides an impervious shield allowing easy clean-up of oil, grease, chemical spills, etc. along with strong protection against impact and abrasives. Simply power wash or use soap and water.

Is it safe to prepare food on a surface coated with Rust Bullet for Concrete?

Rust Bullet has not obtained certification from the Food and Drug Administration (FDA) for use on surfaces that come into contact with food or water or food service equipment; we cannot recommend Rust Bullet for Concrete be used in that capacity.

How do I maintain my concrete that has been protected with Rust Bullet for Concrete?

Rust Bullet for Concrete should be inspected annually for any visual cracks or chips. If any breaches in the coating are found, simply scuff the problem area and apply an additional 1 to 2 coats to that area. If your concrete floor is subjected to high traffic and/or heavy machinery, a biannual inspection should be implemented. Using a dry film gauge is a great method of checking for coating ware.

Industrial

Is Rust Bullet appropriate for Industrial and Commercial projects?

Yes. Rust Bullet Standard Formula (Gold Label) is appropriate for most industrial or commercial type projects. A minimum dry film thickness (dft) of 12 - 15 mils is recommended for most industrial and commercial applications. Rust Bullet will provide superior protection even under the harsh conditions common in industrial and commercial environments. It protects surfaces with an impenetrable, nonporous, armor-like shield that repairs, defends and maintains surface integrity. Rust Bullet’s Patented Technology is UV resistant, scratch, chip and chemical resistant and provides outstanding protection from abrasives and corrosives that damage and destroy surfaces.

Rust Bullet is a one part multiple coat urethane that can be applied with little or no surface preparation, reducing the high cost of product, labor and the containment of waste. Rust Bullet requires little or no maintenance, consequently saving money and minimizing down time. If surface preparation is necessary, Rust Bullet Metal Blast can be used to dissolve rust and properly etch the metal prior to the application of Rust Bullet. Always allow the surface to completely dry before applying Rust Bullet. Although it is not always necessary to blast surfaces prior to a Rust Bullet application, Soda Blasting, Dry Ice Blasting and Hydro-Blasting are three methods of media blasting that are effective, clean and environmentally safe. All media are sound options and clean up will be relatively minor. Surface Prep on industrial and commercial projects may vary dependent upon the condition of the substrate.

What is Dry Film Thickness (dft)?

Dry Film Thickness (dft) is the thickness of a coating when dry, expressed in mils. One mil is equal to one thousandth of an inch. 1 mil = .001 inch (1/1000). For comparison purposes, 4 mils is approximately the thickness of one sheet of standard paper. Most black plastic trash bags have a thickness of about 1.5 mil although heavy duty bags may be about 3 mils.

How do I know what the recommended dry film thickness (dft) is for my project?

The higher the mil measurement of Rust Bullet's dry film thickness (dft), the greater the protection provided. Generally industrial or commercial type projects require a minimum dft of 12 - 15 mils; however, many variables should be considered when determining the desired dft for any project. Some of these variables to consider are: The existing condition of the surface being coated and the surface’s exposure to:

  • Moisture
  • Harsh chemicals
  • Abrasive objects
  • The damaging effects the surface must endure from environmental conditions and exposures

How do I ensure the finished project has sufficient mil coverage?

The most accurate way to measure dry film thickness is to use a mil gauge. Apply an appropriate number of coats to achieve the desired dft for the appropriate protection for your project. Refer to the chart below to determine the theoretical coverage of Rust Bullet Coatings (70% solids by volume). This theoretical coverage does not take into account transfer efficiency which will vary dependent upon application equipment, applicator and atmospheric conditions during application. The number of coats needed to achieve the appropriate dft will depend on the chosen method of application: brush, roller, HVLP Spray System or Airless Spray System.

How does Rust Bullet compare to an epoxy primer?

An Epoxy Primer is not an anti-corrosive coating and will not furnish the protection provided by urethane's such as Rust Bullet Coatings. Urethane coatings provide a high degree of chemical and moisture resistance as well as excellent adhesive properties. Additionally Rust Bullet Products have demonstrated a high competition with epoxy coatings due to the ease of application, one-component product and ease of repair, when necessary. A properly applied and cured Rust Bullet Coating will not break like the epoxy and powder coatings. Although Rust Bullet Coatings do not require a catalyst for curing like the Epoxy coatings, using the Rust Bullet Rapid Fire Accelerator will decrease the curing time by up to 80%.

If an epoxy finish is desired, and the existing surface is an epoxy finish, scrape off any loose rust and epoxy coating, rough-up the remaining tight epoxy with 100 grit sandpaper prior to applying Rust Bullet then re-apply the epoxy coating over the final coat of Rust Bullet. Please note: For best results, the surface should be prepared down to bare metal, removing as much of the existing failing coating as possible. Rust Bullet works best when it is in direct contact with rusted or clean metal.

Will Rust Bullet protect my galvanized metal roof?

Yes. Rust Bullet is the ideal coating for protecting galvanized metal buildings and roofs. It not only provides protection from rust and corrosion, but will actually make your metal roof stronger and more weather resistant. Following the application guidelines, application of Rust Bullet Coatings to a clean galvanized surface will exhibit no issues with adhesion or compatibility. Rust Bullet applies easily and quickly by brush, roller or an airless spray system. Costly roof and building replacements can be avoided by simply applying Rust Bullet.

What is the recommended application method for galvanized corrugated roofs?

The recommended application method for Rust Bullet on Galvanized Corrugated Roof projects is an airless spray system with a 517 to 523 tip at approximately 3000 PSI. Multiple coats should be applied to achieve the recommended dft (dry film thickness); each coat of Rust Bullet will add strength and durability, increasing the life of the roof.

Will Rust Bullet protect metal from magnesium chloride?

Yes. Rust Bullet will perform well to protect metal from direct contact with magnesium chloride. Magnesium chloride is used as a de-icer on roads in many states. It is very corrosive will cause significant damage to concrete and metal. It will affect substrates in two ways, either by a slow rate or a fast attack depending on the concentration and the conditions and circumstances. A very high concentration of magnesium chloride on a frequent basis will reduce the protective properties of any corrosion control coating, including Rust Bullet. Rust Bullet with its armor tuff coating will last longer and provide better protection than any other product available. A dry film thickness (dft) of 12 -15 mils is recommended for surface that will come into contact with magnesium chloride. Regular inspection of the surface to identify any breaches in the coating for immediate and easy repair is always recommended.

Is Rust Bullet an appropriate coating for use on an air duct?

Yes. Rust Bullet will provide excellent protection for an Air Duct System. We recommend not running air through the system for at least 72 hours after the final coat of Rust Bullet has been applied. Rust Bullet will encapsulate the rusted areas adding strength to the coated surfaces.

Does Rust Bullet contain lead or chromates?

No. Rust Bullet Products do not contain lead, zinc, chromates, acids or heavy metals.

Will fertilizer and lime affect Rust Bullet?

No. A properly applied and cured Rust Bullet Coating (Rust Bullet Standard Formula) with a Rust Bullet Clear Shot topcoat will hold up extremely well to fertilizer and lime. For best results apply thin even coats of Rust Bullet Standard to achieve the minimum dry film thickness (dft) of 12 - 15 mils. and 2 to 3 coats of Rust Bullet Clear Shot as a top coat. A regularly scheduled inspections and maintenance program is recommended for all harsh environments, allowing for immediate identification and repair of any breaches or imperfections in the coating.

Is Rust Bullet compatible with cadmium?

Yes, Rust Bullet is compatible with cadmium. Cadmium is mostly used in the electroplating of metal and steel. It is used as a form of corrosion protection. Before applying Rust Bullet on electroplated surfaces, the surface must be clean and free any contaminates. We recommend cleaning and etching the electroplated surface with Rust Bullet Metal Blast to ensure proper adhesion.

What if my project requires a faster re-coat time?

Rust Bullet Rapid Fire Accelerator was designed to be added to all Rust Bullet Coatings to decrease the normal recoat time of 2-6 hrs to approximately 30 - 40 minutes per coat. Rapid Fire makes it possible to apply multiple coats of Rust Bullet in a single day and reduces project completion time by as much as 80%. Rust Bullet Rapid Fire Accelerator is designed for spray applications. A Rust Bullet coating accelerated with Rapid Fire can be applied with either an HVLP Spray System or an Airless Spray System.

IMPORTANT: Rapid Fire is to be added to the Rust Bullet coating at the job site; it cannot be added until you are ready for application. As soon as Rapid Fire has been added, the curing process begins. Pot life is approximately 4-6 hours. Only mix Rapid Fire Accelerator into the quantity of Rust Bullet that will be used within a 4-6 hour period.

Will I have problems Rust Bullet if I am located in an area with high humidity?

If humidity is too high (80% +), it will adversely affect the curing and adhesion process. A couple of things can be done to minimize the theses effects. One is to provide air circulation or an air flow that vents the air away from the coated surface. This may assist in reducing the humidity, but may also circulate particles and debris that may become embedded in the wet paint. Secondly you may apply Rust Bullet by brush. A brush application tends to trap less air and moisture and is therefore the best application method in a high humidity zone. Apply additional, thinner coats rather than fewer, thicker coats. This will help eliminate the formation of bubbles or blisters on the coating surface which can occur if the solvents cannot be expelled. The formation of humidity bubbles or blisters can result in poor adhesion, which in turn, may need re-sanding and a touch up.

Can Rust Bullet be used instead of standard military paint?

Yes. Rust Bullet is currently used by many divisions of the United States Military. Rust Bullet has strong resistance to chemicals and abrasives in addition to its superior patented technologies for controlling rust and corrosion. Based upon the attributes of a properly applied and cured Rust Bullet Coating, it may be used as a chemical agent resistant paint system. Rust Bullet can be easily top coated with the Rust Bullet BlackShell, WhiteShell, and ColorShells which are ANSI Compliant OSHA Safety Colors, as well as other standard military topcoat paints. Rust Bullet has been awarded a Schedule Contract with the General Services Administration (GSA), allowing qualifying entities to purchase from the GSA Schedule.

Marine

What is the recommended method of application for marine use?

Rust Bullet coatings can be applied by brush, roller or spray equipment. An airless spray system using a 517 or a 523 tip at 3000 PSI pressure is the suggested method for Marine, Industrial, or other commercial applications. A minimum dry film thickness (DFT) of 12 mils is recommended. It is recommended that before and after each coat of Rust Bullet is applied; the pump, lines, and sprayer be flushed with Rust Bullet Solvent . It is essential to keep the application equipment clean and the line free of any build up of Rust Bullet product.

What are the recommendations on surface preparation or media blasting?

The substrate must be free of loose rust, paint, moisture, dirt, mildew, oily substances, wax and loose particles. It is extremely important to remove embedded salts (chlorides) from the surface prior to the application of a new coating system. The surface to be coated must be completely dry. Although it is not always necessary to blast surfaces prior to a Rust Bullet application, Soda Blasting and Dry Ice Blasting are two methods of media blasting that are effective, clean and environmentally safe. Both media are sound options and clean up will be relatively minor including the drying procedure after the dry ice blasting.

Are additional coats of Rust Bullet required for marine applications?

It is recommended that a minimum 12-15 mil dft for any Marine or Industrial applications for optimum protection. Rust Bullet can be applied by brush, roller or spray equipment. The application method used will determine the number coats that are needed to achieve a minimum dft of 12-15 mils. When using a roller or airless sprayer, three to four coats of the Rust Bullet Standard Formula will generally achieve a dft of approximately 12 mils. It is our experience that a brush application will generally achieve a 1.5 - 2 mils dft per coat.

Is there a recommendation of the number of coats for a ship submerged in seawater and what is the effect of saltwater on Rust Bullet?

A minimum 12 - 15 mil dft (dry film thickness) is recommended for Marine applications. Additional coats or mils may be needed for adequate protection dependent upon substrate and exposures. Sea temperatures vary as does the salt content; these factors may also help determine the appropriate dft. Salt water should have minimal effect on Rust Bullet. Refer to ASTM B117 Seawater Spray (Fog) Test Results and ASTM D870 Seawater Immersion Resistance Test Results for further technical and engineering data on salt water exposures.

What is a marine tie-coat and when should it be used?

A Marine Tie-Coat is a general purpose chlorinated rubber type product used on metal surfaces and as a tie coat between different types of coatings. This versatile product can be used successfully above and below the waterline and over a variety of coatings as a tie coat. It is generally compatible with anti-fouling bottom paints and various types of topside finishes.

As Rust Bullet contains aluminum, when it is applied to a hull, the hull must then be treated as an aluminum hull. As most anti-fouling paints contain copper, applying it directly onto a cured Rust Bullet coating would create an undesirable Dissimilar Metal (Galvanic) Corrosion. This galvanic corrosion occurs when two dissimilar metals (in this case aluminum and copper) are in contact with each other in an electrolyte (salt water). Due to the distance between aluminum and copper in the galvanic series, a non-conducting insulator (e.g. rubber) should be placed between them or they must be isolated from the electrolyte. On an ocean-going vessel the isolation is not an option and therefore the tie-coat must be applied.

Does Rust Bullet recommend the use of anti-fouling paint?

Rust Bullet provides durable surface protection that is scratch, chip, chemical and UV resistant. Anti-fouling bottom paints reduce or eliminate marine growth that develops on a boat’s underwater surface. Anti-fouling paints do this by using chemicals that slowly release to repel underwater aquatic life. Most anti-fouling paints require a chemical reaction with the surface to which it is applied for proper adhesion. If you do use anti-fouling paint, please refer to the Rust Bullet Marine FAQ regarding the use of a Marine Tie-Coat. Always check with the anti-fouling paint’s manufacturer before applying an anti-fouling paint over Rust Bullet.

Is Rust Bullet recommended for use on the inside of small engine gasoline tanks?

No. Rust Bullet is not affected by gas itself, but was not designed as a small engine tank sealer on the inside of a small engine gasoline tank. We have not tested for this application and can offer no promise as to what the outcome will be if used as such. Rust Bullet can be used on the exterior, but it was not designed for internal use on a small engine gas tank. There is no guarantee the inside of the tank is covered evenly or thoroughly. The inside of the tank does not receive proper air circulation for the coating to cure properly.

Can Rust Bullet be applied to an aluminum hull?

Yes; Rust Bullet can be applied directly to the clean surface of an aluminum hull. Etching the aluminum surface with Rust Bullet Metal Blast prior to the application of Rust Bullet is recommended for optimal adhesion.

Automotive

What are the application methods for Rust Bullet Automotive?

All Rust Bullet coatings may be applied by brush, roller or spray equipment. A brush coat should be applied evenly without buildup in a crosshatch method (up and down and side to side) using continuous motion. Thin even coats using the crosshatch application method will produce the best results. Always keep a wet edge on the tip of your paint brush. The appropriate number of coats should be applied to achieve the recommended dft for your project. Brush and roller applications result in an approximate dft of 1.5 – 2.5 mils per coat. An HVLP spray system applies approximately 2-3 mils per coat, while the Airless sprayer application averages a minimum of 3 to 4 mils per coat.

Can Rust Bullet Automotive be used as a primer?

Yes. Rust Bullet can be used as an automotive primer. Before applying a finish color to a surface coated with Rust Bullet, we recommend apply a high build sandable primer to the coated surface. Rust Bullet produces a very hard surface when cured; therefore, applying a sandable primer to the final coat of Rust Bullet will accomplish two things: remove any imperfections in the coated surface and provide a surface that is easier to sand smooth. It will also allow you the luxury of applying the final color whenever you choose to do so. Many Body Shops use this method to save time and work. Always follow the manufacturer's recommendations.

Is Rust Bullet Automotive compatible with automotive fillers, fiberglass and primers?

Yes. Most body fillers, fiberglass and automotive primers may be applied directly over Rust Bullet. Two coats of Rust Bullet should be applied to the metal surface. The body filler, fiberglass or primer should be applied directly over the second coat of Rust Bullet between the time that the last coat of Rust Bullet is dry to the touch, about 2-6 hours, up to 12 hours. The previous coat should be dry to the touch and not wet or tacky; if there is no transfer of coating to a gloved finger it is safe to apply a filler.  If 12 or more hours have lapsed, wait for Rust Bullet to cure for at least 24 hours then lightly scuff with 150 grit; enough to break the glaze to create a surface profile. This 12-hour period is decreased in areas with high humidity levels.
Please note: Fillers have a tendency to absorb moisture which will cause further rusting of the metal and bubbling of the filler if applied directly to a rusted area that has not been protected with Rust Bullet. Rust Bullet works best when it is in direct contact with the metal.

What is necessary prior to applying body paint?

For best results, the surface should be coated with a high build sandable primer prior to applying the desired automotive finish paint. Always follow the recommendations of the manufacturer of primers, sealers and finish paints for a proper application. Once a Rust Bullet Coating has dried for at least 24 hours, a primer may be applied directly to the Rust Bullet coating after scuffing with 150 grit.

Is Rust Bullet appropriate for undercoating my vehicle?

Yes. Rust Bullet Coatings are ideal for undercoating a vehicle and will provide outstanding protection against corrosives and abrasives. Use the Rust Bullet Automotive formula if you are using HVLP spray equipment for the application.

Is Rust Bullet recommended for use on the inside of small engine gasoline tanks?

No, unfortunately, we do not have a product for the inside of small gas tanks. Rust Bullet was not designed as coating for the inside of a small engine gas tanks. We have not tested for this application and can offer no promise as to what the outcome will be if used as such. When using Rust Bullet Coatings, you must ensure the coating is applied thinly and evenly, and there is no guarantee the inside of the tank is covered evenly throughout. Additionally, the inside of the tank does not receive proper air circulation for the coating to cure properly either. Rust Bullet is not affected by gas itself, and can be used on the exterior.

Is Rust Bullet recommended for use on an exhaust system?

No. After curing, all Rust Bullet coatings have a service temperature range of 314 F (157C) continuous, and can tolerate maximum temperatures between 617F (325C) for up to 72 hour periods. Rust Bullet provides excellent protection for most engine components; however, is not recommended for coating exhaust systems due to the excessive heat produced on headers, exhaust manifolds, catalytic converter or exhaust pipes.

Can I apply Rust Bullet under a truck bed liner?

Yes. Rust Bullet provides excellent surface protection under bed liners.

What are the recommendations for spraying Rust Bullet Automotive or the Top Coats?

Rust Bullet Automotive can be applied through HVLP spray equipment using a 1.7 to 2.0 tip with 40 - 60 psi. BlackShell, WhiteShell and the ColorShells can be applied also with an HVLP, with a 1.5-1.7 tip and 40-60 psi. This method will achieve a dft of approximately 1.5 - 2.0 mils per coat. It is important to run Rust Bullet Solvent through the spray equipment prior to spraying the first coat of Rust Bullet Automotive to remove any moisture that may be trapped in the equipment. After the application of each coat of Rust Bullet Automotive, flush the gun or submerge the tip in Rust Bullet Solvent. It is important to keep the equipment and sprayer clean. If the spray gun has a filter, it must also be cleaned. NOTE: If Rust Bullet Solvent is unavailable in your area, Xylene, Toluene or Acetone may be substituted.

House & Farm

Will Rust Bullet protect my metal roof?

Can Rust Bullet be used on wrought iron fencing, furniture, and fixtures?

Yes. Rust Bullet Standard Formula (Gold Label) will provide superior protection from corrosion and abrasives to wrought iron fencing, furniture and fixtures, adding years of life to the integrity of the wrought iron.

Can Rust Bullet be applied to stock drinking tanks?

Rust Bullet does pass the Environmental Protection Agency (EPA) Standards for Potable Water; however, Rust Bullet has not been approved as a coating for containers for food or water consumption by the Food and Drug Administration (FDA). Until Rust Bullet has obtained certification from the FDA for use on surfaces that come into contact with food, drinking water or food service equipment, we cannot recommend Rust Bullet Products be used in that capacity.

How many coats of Rust Bullet are required for my project?

Rust Bullet requires a 6 – 12 mil dry film thickness (dft) for Home and Farm applications. This requirement will vary depending upon the type of application. The higher the mil measurement of Rust Bullet’s dft, the greater the protection provided. Many variables should be considered when determining the desired dft for any project. Some of these variables to consider are; the existing condition of the surface being coated and the surface’s exposure to moisture, harsh chemicals, and abrasive objects. The damaging effects the surface must endure from environmental conditions As Rust Bullet cures, it releases carbon dioxide gas while dehydrating the rust. This process may create small pin holes in the first coat of Rust Bullet. The second and successive coats will seal these tiny pin holes and form an air-tight, armor-like shield over the application surface. If these pin holes are not sealed after the first coat, air and moisture may penetrate the Rust Bullet, allowing rust and corrosion to form.
