I just bought a few bottles of this stuff at the local auto parts store and I am VERY impressed. I am assuming it is a light compound because it claims to remove 1500 grit sanding scratches, and boy does it ever. It's virtually foolproof as well, even when I don't buff it enough, it leaves no scratches on the car. I follow it up with some FI2 and it really works wonders. Just thought I'd share it with you folks. Never thought I'd find a good miracle worker at the auto parts store!
