Anyone with experience with welding sheet metal? My 54 needs some panels replaced and I bought a gas MIG welder to do the work. I have some butt weld clamps to ensure proper spacing, but I have never used them. Another friend said he would only weld panels after crimping a flange in the body and cutting the panel to fit in the flanged area. What do you all say about the options? Is it worth buying a flanging tool and learning to use it, or just butt weld the sheet metal as is?
