I was washing my teg today, and after washing and everything I decided to try out the clay bar. My first time using it. When I got the clay, it came with that spray you use also. Well when I started using it, like some of the clay got smuged into my paint and I tried to remove it but it wouldn't come off. Is there any solution to this? I don't know if I'm using it right, but I don't think it really works, maybe I'm wrong. I followed the directions and everything. It's only smuged in one area that I was working on, but in other areas it's fine. I was also working in the shade.
