WEN Products has a rich history of producing car care items. WEN is proud to have designed and produced power tools since 1951, and in fact, WEN pioneered the random orbit technology that is in use in virtually all waxers today. These bonnets fit 9 inch and 10 inch waxers. Each package contains 2 bonnets that are made with 100-Percent cotton and designed to be extra soft. These polishing bonnets are designed for use in removing wax and buffing. Make sure to use specially designed bonnets, so you won't damage your car's finish.
