As an auto rust inhibitor, it is perfect for all your automotive applications, including undercarriages, frames, floor pans, rocker panels, suspension, and much more.

Use Rust Bullet Automotive Formula as a stand-alone coating, or in combination with Rust Bullet BlackShell, WhiteShell, DuraGrade Color or Clear Shot for unbeatable rust protection. Rust Bullet Automotive is metallic gray in color. Rust Bullet Automotive can be brushed, rolled or sprayed. 
 We want you to experience optimum performance and enjoy the protective benefits of our coatings, so please follow our simple Application Guidelines prior to starting your project to set yourself up for success!

The surface to be coated must be completely dry, have a profile for adhesion, and the recoat time of approximately 2-6 hours must be followed. As soon as the previous coat is dry to the touch, you are ready for the next coat.
