Por 15 vs. Rust Bullet

Well, us. Right? Use our rust inhibitive coatings to stop rust on Industrial, Commercial, Marine, and Home & Farm Applications. Rust Bullet stops rust, the application is easy with no preparation, and is better for the environment than our competitor’s products, to put it simply. While we respect what Por 15 tries to do, we meet hundreds of customers who have tried the product and have found that it’s just plain difficult to use. When used correctly, when all steps are followed* (the operative phrase here), it tends to ‘hold up okay,’ but unless all of the metal you are painting is completely saturated with the product, it will rust underneath the Por 15 coat. A few other downfalls to the Por 15 product is its smell, as it does not use Low V.O.C. chemicals, its sensitivity to humidity, and the prep to use the actual product.



In an effort to better our product and brand, we set out to test our products against our immediate competitors. Rust Bullet is proud to inform its customers that its products have been awarded unprecedented two patents for its superior technology and environmental friendly rust preventive products. With this endeavor, Rust Bullet has left competitors like POR 15 far behind in the quest for rust prevention. Rust Bullet simplifies rust prevention by eliminating the need for extensive surface preparation. Rust Bullet simplifies rust prevention by eliminating the need for extensive surface preparation. The Rust Bullet products can be easily applied to the car surface either in the form of a paint, spray or even rolled. There is also no requirement of a top coat or an undercoat which reduces the overall time. While products like POR15 simply provide a coating on the car surface, the Rust Bullet products are specifically designed to penetrate the metal surface and mix the rust. This feature helps in better rust prevention for the products and attacks rust right at the root level thus offering better protection. The Rust Bullet products are also more environmentally friendly as compared to other products in the market. These products are developed to emit lower emission which makes them more sustainable. The products are free of heavy metals, zinc, chromates and other harsh chemicals. Rust Bullet ensures protection for both your assets and the environment.

It is true that many rust conversion products claim to change the chemical nature of rust and convert it to a more stable element that won’t rust again, this isn’t really possible. Most of these failed products just simply don’t work, or work, but not for more than a few months at best, and they are subject to the same chipping and cracking that occurs with ordinary rust coatings.The physical integrity of the metal coating is as important as its chemical barrier properties in many applications. Selecting the best metal coating for an application requires evaluating all effects of the specific environment, including thermal and mechanical conditions. Many new materials have been developed, but steel remains the principal construction material for automobiles, appliances, and industrial machinery. Because of steel’s vulnerability to attack by aggressive chemical environments or even from simple atmospheric oxidation, a metal coating is necessary to provide various degrees of protection, ranging from hot-dipped and the electroplating process, to tough polymers and flame-sprayed ceramics. In general, corrosive environments contain more than one active material, and the coating must resist penetration by a combination of oxidizers, solvents, or both. Thus, the best barrier is one that resists “broadband” corrosion.

One of the most common and inexpensive protection methods for steel is provided by a metal coating process with zinc. Zinc-coated, or galvanized, steel is produced by various hot-dipping techniques, but more steel companies today are moving into more environmentally friendly methods of protection. (Like us!)

What POR-15 Does:

POR-15 chemically bonds to rusted metal and forms a hard, non-porous coating that claims it will not crack, chip, or peel. It states that it will keep moisture away from metal with a coating that is strengthened by continued exposure to moisture. Thereby combatting the rusting process.

What Rust Bullet Does: 

When Rust Bullet is applied to rusted metal it penetrates the substrate, dehydrates the rust, until it reaches the metal underneath. This allows the resin to become intertwined with the rust, then becomes part of the coating and solidifies into an armor tough coating with phenomenal adhesion.

According to extensive independent scientific testing, Rust Bullet is the most effective, longest lasting, easiest to use rust/corrosion-control product on the market.


Let’s begin by discussing what a rust inhibitor is and how it works.

Q: What is a rust inhibitor?

A: Rust inhibitors use proprietary chemicals to prevent rust on iron, iron alloy, and other metallic surfaces. Rust Bullet restores virtually any substrate to a rust and corrosion free usable state.

Q: How does a rust inhibitor work?

A: Using a single component high solids industrial coating, Rust Bullet provides protection from corrosion and prevents its return. Paint or spray Rust Bullet over rusted metal or metal capable of rusting, and then the miraculous adhesion properties of Rust Bullet will effectively seal rusted areas and prevent further rusting.

Q: What applications are available for rust inhibitors?

A:     Industrial: Highway bridges | Metal equipment | Oil wells | Cranes | Wastewater treatment plants

Home and Farm: Workman’s tools | Tool boxes | Farming equipment and machinery | Garages | Storage sheds

Marine: Ships | Ports | Boats | Transport containers | Anchors

Automotive: Motor vehicles | Railroad cars | Dry-van trailers | Refer trailers | Old engines

Concrete: Showrooms | Warehouses | Driveways | Platforms | Patios

Q: Should I wait until my metals are rusty before using a rust inhibitor?

A: While it’s okay to use Rust Bullet on heavily rusted items, you can also deter or prevent the development of rust with Rust Bullet. Combating rust before it starts to accumulate is the surest way to keep your products in optimal condition.
