Abstract: Plastic restoration kits and methods effectively the light transmission and optical clarity properties to a plastic light cover on an automobile or other plastic surface such as a sunglass lens or corrective optical lens. The kits and methods restore plastic surfaces that have been damaged by scratching and/or UV-induced oxidation. The kits and methods utilize polishing and lusterizing compositions having particles selected so as to polish and lusterize a plastic surface and a UV protective composition that forms a hard UV protective coating. 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.
