摘要： The present invention is directed to a process for resurfacing a damaged surface of plastic lenses, such as vehicle headlights and taillights to restore the plastic lens surface to its original clarity and transparency. During process, a cleaned damaged surface is preferably orbital sanded with a moistened sand paper disc mounted on a sander for removing visible scratches and yellowing of the moistened damaged surface of the plastic lens. Thereafter, the sanded surface is preferably rotary polished with the slush-resistant polishing composition of the present invention applied on a polishing pad mounted on an polisher for removing any visible score marks that may have been created during the sanding step. Then, the polished surface is preferably rotary finished with the slush-resistant finishing composition of the present invention applied on a finishing pad mounted on a finisher for removing any visible swirls marks that may have been created during the polishing step.
