85 Cutlass Brougham said:Heat is a no-go as I would need to strip it all off and start anew. Plus, heat has the potential to do way more harm than good on such a big piece of metal. I could warp it far worse than it is, and make the panel unusable. You also have to consider that I started the body work in 1999 and am not completely sure what is under there, or what I did in every area. ( I painted it once, but the paint failed before I could get enough money to put the car together.) Anyhow, what I did seems to have worked ( Success after 40+ hours of trying!!!) and I finished it this morning when I couldn't fall back to sleep at 7am. It's in primer now, and I will let it cure for a few days before I block it in 400 grit and call it a day. Hopefully, it will be entering the paint booth this time next week. If not, then definitely the following week. I have blocked all the flat parts and most of the detail areas of the trunk lid, doors, quarters and sail panels already, and have the front clip, the roof I just primed, the bumper covers and miscellaneous pieces left to sand.
Fair enough. I mentioned it because a guy I grew up with often removed huge dents using a technique he learned from his welder dad. It is almost an artform to get it perfect, but you could often make imperfections less so they could be removed with body filler. Though I'd throw it out there if you wanted to chance it and had an old body panel to work with.
