Use this if the original base material (i.e. metal, fiberglass, carbon fiber, and the like) is exposed.
Apply 2 to 3 light coats of primer to the material you intend to paint.
Make sure you cover all of the exposed original base material.
Allow 5-10 minutes before continuing on to the next step so the primer has time to dry.
Primer technology has advanced nicely over the years, but its usage is the same. It is the first coat that you apply to your paint job. After wet-sanding the damaged area, put down primer to make sure that the paint adheres. Due to its binding properties, primer makes color stick to whatever it needs to stick to. It also acts as a protective coat, fighting rust and other detrimental elements. The lack of a primer can lead to corrosive effects so make sure not to skip this layer.
