Is it worth welding patch panels on the swiss cheese era of Blazers? The steel above the upper trim molding is in decent condition, would I be wasting my time to cut the panels off at that line and weld new below? I realize there's probably a can of worms that would open up with patching and welding around and to the floorpan, structure, etc. I guess that's the stuff I wonder about. Thanks guys!
