I know the bottom section of my doors are going to need some body work when I get my paint done. From where the factory molding used to be down they are not straight, but a little bumpy and uneven, though not too bad. My question is, how does the body shop do this kind of work, pound on the sheetmetal or filler? Is it going to be expensive? Would it be cheaper to look for some perfect replacement doors? Thanks in advance.
