When spraying Rust Bullet Automotive or Rust Bullet topcoats, the following recommendations should be followed for optimal results:

    • Spray Gun Type: HVLP (High Volume Low Pressure)


    • Nozzle Size: For HVLP, a nozzle size of 1.7mm to 2.0mm is recommended.


    • Equipment Preparation: Run Rust Bullet Solvent through the spray equipment prior to spraying to remove any moisture that may be trapped in the equipment.


    • Mixing: Stir the Rust Bullet coating thoroughly by hand before application. Do not thin the product unless necessary; if thinning is required, use no more than 5% Rust Bullet Solvent.


    • Surface Preparation: Ensure the surface is clean, dry, and free of loose rust and paint, oil, grease, and other contaminants. Sand or blast the surface to create a rough profile if necessary. Metal Blast will also clean and condition a metal surface for application.


    • Coat Thickness:
        • Automotive Coating: Apply 2 to 3 coats to achieve a total dry film thickness of approx. 6 mils.

      • Topcoat: Apply 1 to 2 coats, aiming for a total dry film thickness of 2 to 4 mils.
    • Spraying Technique:
        • Maintain a consistent distance from the surface (6-10 inches).

        • Apply in even, overlapping strokes to ensure uniform coverage.

        • Avoid heavy application to prevent runs and sags.
    • Temperature: Ideal temperatures to apply are between 50°F and 90°F (10°C to 32°C). Rust Bullet can be applied in temperatures ranging from 35°F to 110°F (2°C to 43°C).


    • Humidity: Ideal humidity levels are between 40% and 70%. Avoid application if humidity exceeds 85%.


    • Maintenance: After the application of each coat of Rust Bullet, 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.


  • Safety: Wear appropriate personal protective equipment (PPE) such as gloves, goggles, and an organic vapor respirator. Be sure to allow adequate ventilation during application and drying.

Following these guidelines will help achieve a durable and high-quality finish with Rust Bullet Automotive and any Rust Bullet topcoat product. For additional details about application, please refer to Rust Bullet’s application and technical documents.

NOTE: If Rust Bullet Solvent is unavailable in your area, Xylene, Toluene or MEK may be substituted.
