If you are going to paint your plastic panels, you absolutely must use Five Star Race Car Bodies Plastic Primer! There are plenty of low-cost primers available on the market but, the plastic used in Five Star's body panels has a very different composition than the plastic used elsewhere in the automotive industry. Using a basic primer from the local parts store 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.
