ABSTRACT:
Polishing compositions and methods are provided for removing scratches and other imperfections from a variety of plastic surfaces in order to improve clarity and optical quality. Such polishing compositions include a solid polishing material, water, and an organic solvent containing undecane or any equivalent solvent. They can also include a stabilizing agent such as carnauba wax to keep the other ingredients suspended or otherwise mixed together. The polishing compositions are applied using buffing pads made from a variety of materials, including open-cell polyurethane, fleece wool, cotton, or synthetic materials. The compositions are applied by hand or using a hand-held rotary, orbital, or oscillating buffing machine, and are also compatible with existing scratch removal machines, such as robotic machines used to restore airplane windows.
