I just recieved my body parts I orderd from Tabco. I orderd the O.E. replacment rockers, inner rockers as well as inner cab corners. I have mostly done welding of thicker pieces never thin sheet metal before. Plus when I had to weld it never really had to look good too. I did pick up some anit-heat compound from Eastwood. Also, a welder that works at Pratt suggested heating up the metal a bit first with a propane torch to limit warping and practicing a lot before trying to weld the rocker on. Plus I was planning on making small tack welds all around and then fill in the spaces in 1- 1 1/2 inch beads rotating around the rocker panel with the standard drag style technique using .023 wire and 70/25% Argon Co2 mix at about 20CFH or more because I will be welding outside. So does anyone have any suggestions, tips or ricks for welding in the new panels?
