I am wondering does anyone here know what dealers use when they prep the paint of the new car for the customer? I think the wait time is 2 - 3 hours and it looks great when you take the keys, with no spider, swirls, or marring. I am guessing its some sort of filler product. Of course in just a few wash cycles it is obvious you have your work cutout for yourself, because whatever they used covered up all imperfections.
