i am certifed welder doing both mig-tig hammer welding & lead since late 60's but some are afraid to weld from lack of knowledge. find someone local club or class or can literally glue any panel on these days with panel adhesives. i used to think this was cheating but have seen metal torn apart as strong as weld job & don't need to learn to weld or buy equipment. if not doing perfect restoration talk to local body shop supply store for info. on line i think one called bodytool.com has everthing & techs for either way.
