First, let me say how much I've learned on this forum. I've never heard of claying a car before I read about it here. At my local autoparts store the only brand I could find was Mothers. It was a kit with a clay bar, spray detailer, and wax. It was about 18 bucks for the kit. Spray the detailer on, rub it with the clay bar, wipe it off. Then use Mothers cleaner wax. Really kind of easy. My question is, did I do it right? I used a plastic sandwich bag to feel the surface of my Sky like I've read about on this forum. Yes, it was rough. After I clayed and waxed the car it was a world of difference. Much smoother. However, I can still feel a little roughness when I rub my hand over it with a sandwich bag. On a scale of 1 to 10. Before was a 10 and after was a 2. Did I not do it right? Should it be a 1 or 0? Should I have spent more time with the clay bar? It looks great. But, it's a Silver Pearl and looks pretty good even when it's dirty. If you clayed a black, midnight or any dark color on any car, I think it would really make more of a difference. Will claying make the paint last longer and look better longer?
