Pretty big pinholes there Ed ,

I never overlap panels either and butt join all my panels as well, however I use a MIG. I do alot of tacks to keep the heat down but there is the inevitable pinhole from time to time.  I then grind the weld flush.  Using a light behind the panel I check for pinholes.[/quote

I do the same Ed but after i check with the light i hit the pinholes with the mig again, just a quick zap will usually fill them.

Yeah I figured do another round with the welder, the thought of it was making me feel lazy...
