ABSTRACT:
A process for removing scratches and dirt from plastic sheeting, windows, face shields, windshields and other plastic articles that will improve the transparency, optical quality and appearance of the above. More specifically, the process will restore plastic glass replacements that have become so scratched as to have their transparency and optical quality impaired to a state where the transparency, optical quality, and appearance are close to if not equal to, a new article. The process imparts other desirable qualities to the processed article that will become more evident in the attached specification and claims. The process is portable so that the aforementioned improvements in the plastic article may be effected in place; in other words, it is not necessary to remove the article from the vehicle or building to process it.
