So im looking to fill in some seams like where the bumper and the body meet. Can i just pack it full of bodyfiller, and repaint the area? i wanna do the same for the rear bumper, and maybe some other parts of the car. I dont have a welder, and cant afford one. But i have lots of body filler and paint. I can get the bumpers supported with greatstuff foam so it will be rigid. anybody?
