Customer Reviews for Rust-Oleum Stops Rust 12 oz. Flat Light Gray Automotive Primer Spray (6-Pack)

Let's see if we can figure this out, Mikey! Please keep in mind that since this is a primer, we do recommend applying a topcoat to Rust-Oleum Stops Rust Automotive Primer Spray to ensure full adhesion and durability. If the primer is leaving a dusty residue on the surface, you are most likely experiencing dryspray. This occurs most often when users hold the can too far from the surface when spraying - our recommendation is 10-16" from the surface. Effects of dry spray can also happen when temperatures are too high or too low. You can try using a lint free rag slightly damp, and gently wipe the surface to remove the dusting. If it's still rough after doing that, you'll want to sand the surface with a 180 or 220 grit sandpaper and make sure it's clean and dry before recoating.
