3M Marine Clear Plastic Restorer safely cleans and removes fine scratches and haziness from most marine plastics. Its mild abrasives work well on hard plastics like polycarbonate. Clear Plastic Cleaner and Polish is a recommended follow-up to the restorer. It gently cleans and removes residual scratches and other minor imperfections, leaving a like-new shine. This product can be used alone on clear flexible plastics, such as those on canvas enclosures.
Application is easy for both products.
The boater dispenses a small amount of the liquid onto a cloth, applies it with a circular motion, rubs until dry, repeating as necessary. For best results on polycarbonate, the restorer should be applied with a buffing machine.
