I just got a new paint job and the body shop told me not to use a wash mit on it. They gave me a 3M foam pad that is used to apply polish and said to use that. I have used it twice, but it seems to me that it would be more likely to scratch the paint because dirt particles don't really have anywhere to go. What do you guys recomend that won't cause scratches? I use microfiber towels to dry it.
