I have a black 2010 Camaro and I tried to clay it for the second time and again I now have slight marring (i.e. lines in the paint). I know I'm using plenty of lube and I'm only applying enough pressure to keep the clay on the paint. I flatten it like a patty like the video shows. The first time I used DP clay and this evening I used Pinnacle Ultra Poly Clay. I really don't think I'm doing anything wrong but I really don't know. Is it possible that my paint is just so soft that it's going to mar every time it gets clayed? Any suggestions? Thanks.
