WOW-finally got around to using the OP today, i didnt have bad swirling, but it annoyed me. So after washing, claying and taping off the car I started w/ OP on a white polishing pad, that knocked out 90% of the swirling, the second pass took out the rest, it was awesome. I did have to change to a yellow pad for a few spots that had deeper scratches, but just the polishing pad and OP did an amazing job. Im very happy w/ this polish. It does what 83/80 does combined. I like that i just have to change pads and not polishes. It also broke down fine enough on the polishing pad that i just waxed afterwards and it looks awesome. Just thought id share, in case anyone is thinking of ordering it.
