i have clayed my new 7000 miles black car twice in the last 2-3 months. everytime i tried a new product, i would clay the entire car. i didn't do the sandwich bag test. i'm trying out yet another product (pinnacle) so was just wondering if i should clay my new car again. any tips/suggestions would be greatly appreciated, thanks. btw, i tried zaino, blackfire, and pretty soon, pinnacle.
