ABSTRACT:
A method of restoring a discolored automobile headlight lens without removal of the lens from the automobile consistent with certain embodiments involves wet abrading an outer surface of the lens with successively finer grit wet sanding disks, using a low speed rotary or orbital tool having a flexible sanding holder holding the sanding disks, until a smooth surface is achieved exhibiting no discoloration, wherein the wet sanding disks comprise disks starting from approximately 220 to 400 grade down to approximately 2000 grade; polishing the outer surface of the lens with an aqueous paste abrasive polish containing aluminum oxide abrasive particles; cleaning any residue from the outer surface of the lens by wiping the lens with a lint free cloth; and spraying a film forming aqueous polymer dispersion containing an ultraviolet protectant to the outer surface of the lens, wherein the sealer comprises of acrylic urethane copolymers, Hindered Amine Light Stabilizers, benzotriazole UV light absorbers, 1-methyl-2-pyrrolidone, and dipropylene glycol monomethyl ether. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
