yup....i do agree that if u can acess it by hand then bang it with a dolly....but there really isn a problem with the screw idea since the holes are quite small and easily reparable...since hell need to repaint that section anyways the extra little bit of bodywork isnt going to hurt....just follow directions for whatever u use....if it says sand with 60 grit paper then u better do it cause sanding creates a scratch size which the coating best adheres to...using the wrong grit size will cause problems....heck...ive got 1/4 inch holes filled in with bondo....i made sure i bondod both sides of the hole though...
