I heard a lot of this a few years ago and decided to try it out myself. Like the other users wrote, the paint is smoother than a baby's butt after you're done with it. And I'd bet my car that it was better than when I drove the it off the lot simply because most cars sit out in the open for a while before they get sold.The only problem is that it took me 8 hours to do the entire car. I guess if you wait too long in between clay barring, it takes a while to get all the crud off. If you do it more often, maybe twice a year, it should probably take less time.For your reference, I have a Subaru Impreza. Now to try it on my 92 Miata whose paint has oxidized rather badly.
