Bar none, this is the best plastic polish on the market. Whether it's your turn signal lenses, center caps, brake lights, convertible top window or the clear plastic gauge cluster cover, Mothers Plastic Polish will clean, shine and protect the clear stuff with crystal clarity. This is a true polish-you can buff out hairline scratches, smudges, flaws and little nicks, as well as clean away yellowing and stains from your plastic convertible window. Mothers Plastic Polish doesn't stop there-it protects your plastics from the sun, smog, water stains and airborne contaminants with a tough layer of polymers. For those tough jobs, try it with our PowerBall or PowerBall Mini.
