I've been meaning to correct my buddies paint for awhile. It was heavily ridden with severe swirls, scratches, rub marks, marring, you name it... Gave it a serious paint correction. Washed, clayed, Menzerna FG400, polish, and sealant. It came out like a new paint job. Only thing I couldn't get out was where someone keyed his door and rear quarter. Used my Flex Random Orbital. Last two, caught em breakin his neck over the car haha.
