If you are going to paint your plastic panels, you absolutely must use five Star Plastic Primer & no other! There are plenty of primers available on the market but the plastic used in our parts is not the same plastic used elsewhere in the automotive industry. Using any other primer will result in severe paint flaking. So before you paint, be sure you have your Five Star Primer, follow the directions on the can precisely and say goodbye to any paint adhesion problems. Specially formulated to eliminate paint flaking or peeling.
