Can Rust Bullet 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 wet sanding the surface. Wet sanding may be achieved by using 150 to 400 grit sandpaper. After wet sanding, apply an additional coat of Rust Bullet, wet sanding again to a very smooth surface; wait 6 – 7 hours before applying a topcoat (time may vary depending on weather conditions). Rust Bullet produces a very hard surface when curing. An alternate method to wet sanding Rust Bullet is to apply a sandable primer to the final coat of Rust Bullet. This 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.
