I got some CarPro denim orange peel pads about a month ago for a customer's poorly repainted Integra Type R. Unfortunately, the paint was so hard that even 2000 grit was having a tough time removing orange peel from it and hitting it with a wool pad and M100 to remove the sanding marks (after going over with 3000 grit) was having a tough time removing the sanding marks...and once it did, the metallic black paint looked LSP ready. Just freakishly hard paint, obviously not the best test.
Since I haven't had any orange peel issues to deal with, I've been using the pads to remove severe swirls and bird bomb etchings. Pretty amazing how quickly it can remove them (assuming they didn't etch past the clear) and how good the paint still looks after using them. I don't get the hazing I typically get when using wool. So if you have the denim pads, no need to save them for just orange peel.
