Putting in new quarter panels??

[Rev]

I've never done that. I do know you need a spot weld cutter to remove those spot welds one at a time. Then after ecerything is lined up correctly, those spot welds need to be put back in one at a time. The seams were originally filled with lead from the factory. I think most just use "seam sealer" or Bondo to do it now. I'll bet your body shop guru is familiar with all that and can do it well. My thoughts.
