First Introduced in 1979, Klasse All In One Polish will remove oxidation, minor swirls, old wax, and other surface blemishes; leaving a beautiful and deep acrylic shine. Unlike some formulas, Klasse will not penetrate or change paint. Using Klasse AIO is very easy, apply a small amount to a microfibre pad and rub into the paintwork, then buff off with a microfibre towel. There is no need to wait for the product to dry or haze over.
