thanks for that tip. Im looking to replace a damaged area around my taillight. I was planning on cutting it out with an air grinder, and then welding in the new piece of new sheetmetal/new portion of quarter panel in that area from behind. Shops want 2k to repair and paint it, which seems like to much to me. they want to cut the whole panel skin off and put a new one on, all the way up to the door seems.
