hi i had a dent on my wing which i repaired and painted,and lacoured out of sprat cans but the paint was the wrong one but it was close but now ive brough a compresser and all the kit to do the bumpers.so i wanna go over the bit on the wing with the right colour(now i have loads of right colour paint)it is metalic, can i scuff the lacour and paint an clear it or do i have to take the clear all back off then paint and clear?

I would take all the spray can paint off that you can before repainting.
