Primer

If you have an unpainted surface, either bare metal, plastic, rubber, etc., APPLY PRIMER! Primer is made to stick to unpainted surfaces and paint is designed to stick to primer!

If you are painting a bug shield, spoiler, mud flaps, side mirrors, etc., and they are unpainted, you will need to prime them before painting. We recommend using our SEM Adhesion Promoter as the first layer on these surfaces (as long as they are not made of Lexan plastic.) Then follow up with primer, basecoat and clearcoat.

Clean the area of all dust with a tack rag and apply primer to the unpainted surfaces. Let the primer dry and lightly sand with #600 grit wet and dry sandpaper. Make sure you let the primer dry for 30 minutes to one hour before applying the color coat. Primer is also great for filling in small imperfections in the surface.
