INSANE STUFF. I used it with a das6 pro v2 polisher with a lake country HDO orange heavy duty polishing pad on my 2004 honda s2000 and it removed 90% of the swirls in 1 go. only the deeper pits and scuffs are now visible which would require a heavier cut. It dusts quite heavily and takes a bit of work to remove from the panel but that means the pad doesnt gum up and need replacing as often. S20 with a DA seems like an almost fool proof method of bringing sligtly worn aging paint up to almost new looking. would 100% reccomend
