I have 3 layers of upp on my car, and it is pretty slick. 3 weeks ago, I put on the first layer of S100 over it. First of all, S100 has NO cleaning abilities at all, because I noticed that I had sealed in some QEW waterspots underneath the wax. Oh well. Last weekend, I QEW'd the car again (in the sun), and now all those waterspots are gone. Did all the S100 wear off or get washed off already?
