reworking a fully restored car

Well the Mopar Rescue Team came over after dinner last night and what I assumed would be a few hours over a couple of nights was actually an hour and the frames are done . They brought a 110v hobart flux wire unit that ran off a 15 amp breaker without any hiccups , I had asked the son to just do the perimeter of the U channel screwed inside the frame rail and the top flanges and down the inner side thinking we could do the bottom and outer side later , it would have been a lot easier to do those beads with the car up in the air but he got on a roll and aside from some patching of the bottom where it was too thin and blew out the job is done . Yippeee now to wait for the floor extensions to arrive before doing the floor and the rest of the panels . I'll post pics in a day or two after I get the grinding and the priming done .
To be honest there folks I am much happier paying a good welder to do this than risking it coming apart , I had thought that a spot welder would be a clean way to replicate what the factory did when they built the car , if the welds are going to be suspect I may just use it for joining all the new sheet metal together then have everything final welded after it is all in place for safety .
