I apologize for leaning on the expertise of hambers so much lately for this bodywork. I'm trying to knock out a few nagging trouble spots till I can think about primer. I hit this thing and it laughs. the roof flexes and nothing happens. I have insulation glued on I really don't want to remove(jute, etc) because it'll be a huge mess and a pain. so I can't get a dolly under the metal even if I could reach. Its about 3" of slightly proud metal in a sea of bondo above the middle of the rear window about a foot. Any thoughts or suggestions? Thanks gentlemen! I can't wait to primer this turkey and show it off!
