Has anyone else had a bad experience of marring from Claymagic claybar? When I first found out about claying last year I bought one, and it worked great. I just bought a new one a couple months ago, and just used it for the first time on my black Bonneville. I just did the hood mostly since I had just clayed it when I first bought it (with the last claybar). I used it with soap which I've done before, and after drying the hood looked like garbage. It was lubed enough because it wasn't dragging or anything. But when it was dried, it looked like I had rubbed the paint with steel wool or something. It polished out easy enough, but I'm afraid to use it after this. Think it could be just a bad piece of clay?
