Hey my parents car just got a fresh paint on their car , and it feels like they're sand or grime in the paint, the body shop says that buffing the car will take it out? Car has a Ful-Thane 2K Urethane. The paint looks dull, and has some drips, does anyone think if i buff it or clay the whole car will it smoothen out? I have to wait a month anyways before i can buff it out since the paint has to cure. Anyways let me know, worried about the paint job, they refuse to do anything about it.
