Body help/advice needed

Rod. But welding panels is the way to go. A bit of advice when welding tack weld around the panel moving your next weld to the opposite side of the panel. Keep and air line and blow gun close. Weld a spot and blow it til cool to touch. This will eleminate warping the panel. Most people will tell you grind the weld with a disc. You can do it that way. But you can warp the panel just as bad if your not careful. I would suggest buying a burr and cleaning up the weld with the burr until you are close to level on the panel. Then switch to a 50 grit disc for final clean up. When finished grinding hammer and dolly as much of the weld as s possible to fix any high or low spots on the panel. Pull a tight coat of duraglass over the weld as a base. Then you can start your filler work .
