I had horrible swirls marks, and marring on my car. Well, after 6 hours, Many washes, few passes on the PC with Menzerna IP, FP2, and a few coats of z5 and then z2...i'm VERY happy. 90% of the swirls are gone. I have never seen paint this clean before on any car. Just wanted to say thanks to everyone who helped me out on here! Here are some pics.
