I had my car transported recently, and there were some contaminated water stains on it's return voyage home, that settled on the roof. It was protected with Adam's Quick Sealant, but nonethless they etched a bit. I've hit em with IPA, and that diminished them slightly. But folks with my eye will still notice them..... Do you guys know of any way to remove them, obviously without polishing? Is there a product you guys have seen success with removing contamination from flat paint/clear? Secondly. I wrench on my own cars a bit, which includes leaning into the engine bay to some degree. And right now I'm KILLING my lower back from leaning over, without touching the paint. Do you guys know of a "jumbo" super-soft microfiber (say in the 24x36 or 36x36, etc) that wouldn't mar the paint, for when I need to lean on the ride? My babies are swirl-free and I'd like to keep em that way!!! So if it's not CRAZY soft, I'll stay away. But I just can't seem to find one in a bigger size. Thanks dudes!!
