Auto polish is a product widely used for cleaning and shining cars, as well as for restoring the surface of dull or scratched paint. There are several synonyms for auto polish that may be used interchangeably. These include car wax, car sealant, and leather or vinyl protection. Car wax is a specialized polish designed for use on painted metal and provides a high-gloss finish that enhances the shine and color of a car's paint job. Car sealant is another type of polish used to protect a car's surface from UV radiation, dirt, and moisture. Leather and vinyl protection products are used to shield a car's upholstery and dashboard surfaces from stains, fading, and damage caused by exposure to the sun.
