Restore plastic headlight lenses and boat windows with our premium headlight restoration kits and plastic polishes. Today's headlights and boat windows are usually made of a very hard plastic, like polycarbonate, acrylic, or Plexiglas. When these plastics oxidize, they become cloudy and yellow. Boats have the added challenge of salt etching. The good news is that you can restore your boat or RV's hard plastic surfaces with a headlight polishing kit or plastic headlight polish. All the products here are designed for the restoration and maintenance of plastics, including headlights, plastic windshields, and windows.
