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.
