A couple of months ago I was shopping to have my bumper resprayed. I decided it wasn't that bad and that I'd pass on painting it for now. Well, I noticed a stress fracture in the left front fender. It is about 1/2 an inch long. Went to several body shops and I am getting the same old somg. $600 to $700 spray the bumper and repair the stress fracture. I was also told by one shop that a flex agent shouldn't be added to the paint because the paint won't stick as well. Any advice would be appreciated.
