Recently I had some scratches on my vehicle due to an incident at a carwash. They set me up with a body shop who wet sanded the scratches and probably used some type of compound. They must have done a quick job because now I can see what looks like swirl marks im guessing from a buffer they used and some hazing in the areas where they wet sanded. I don't really want to bring it back to them. Is there anything I can do myself to remove these? Would a clay bar work?
