Here's a cool trick the guys at Recon showed us. In really confined areas, you will sometimes need to cut away sections of a panel to get to the spot welds, like where the quarter-panel meets the wheelhouse. These two panels are spot-welded together at the wheel lip, and that can be an awkward place to get a drill into. So Aguayo cut pleats into the remaining sections of the quarter-panel and peeled them back individually. This worked better than just trying to peel off the whole thing in one big section. Because sheetmetal is strongest where bends and body lines are stamped into it, the wheel arch is the strongest section of the quarter-panel. The force required to pull it away in one piece may have damaged the wheelhouse behind it.
