yeah, if he wet sanded it I doubt its passed the clear. After you wet sand the paint it def looks bad as if its scratched or needs to be re painted. I think the best bet is to use a higher grit sand paper and go over what he did just a little. Try getting it wet, if the paint looks normal when its wet, but scratches show when its dry then some Meg's ultimate compound will def get that out. I wet sanded a couple scratches on my car and used some touch-up paint, if your patient its really hard to make a mistake that will require something other than a little touch up paint. I have wet sanded before and noticed some swirl marks still show so I just went back with the Megs ultimate compound and it came right out.
