Title: UV protective coating composition and method

Abstract: Plastic restoration kits and methods for restoring the light transmission and optical clarity properties of plastic surfaces, such as plastic aircraft windows, automobile plastic headlight covers, plastic sunglass lenses, and plastic corrective optical lenses. The kits and methods restore plastic surfaces that have been damaged by hazing, scratching and/or UV-induced oxidation. The kits and methods employ at least one polishing composition configured to improve clarity by removing scratches. A UV protective material is incorporated into at least one of the polishing compositions so that the UV protective material becomes worked into the plastic surface during polishing, and a protective coating that forms a hard protective coating over the plastic surface impregnated with the UV protective material is finally applied. The plastic surface may be heated after polishing and prior to application of the protective coating material.
