Abstract: Plastic restoration kits and methods for effectively restoring the light transmission and optical clarity properties to a plastic surface such as an aircraft window. The kits and methods restore plastic surfaces that have been damaged by scratching and/or UV-induced oxidation. The kits and methods employ a polishing composition and optionally a lusterizing composition, each having particles selected so as to polish and lusterize a plastic surface. After polishing and lusterizing, a UV protective composition that forms a hard UV protective coating is applied. The polishing and/or lusterizing compositions may include agglomerated abrasive particles dispersed in a liquid or gel carrier that progressively break down in size when exposed to oxygen and mechanical pressuring during polishing or lusterizing.

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.
