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 all 6 inch waxers. Each package contains a wool bonnet that is designed to be extra soft. These wool bonnets are designed to give vehicles a super luster finish. Make sure to use specially designed bonnets, so you won't damage your car's finish.
