Where you all get your weld through primer these days?

That said, I use it in both modern collision and restoration, but only where its "pinched" between two pieces of steel...

Would you consider welding on angle iron that runs the length of a 1954 truck bed on either side at the bottom just above the wood planks a pinch weld? I plan on drilling holes in my angle iron every 6 inches then mimicking spot welds (aka rosettes) in those holes to the bed sides using my MIG. I plan on using weld through primer on the back of each angle iron and along that line on either bed side.

I wouldn't call that a pinch weld. If you are going to drill holes for the spots I think I would just use something like Rustoleum primer between the pieces of metal. Maybe someone else will chime in on this for more info.

I got nothing for that bed repair, but I'd only recommend that anyone welding through zinc ought to be careful about fumes. I know people who have died from welding galvanized pipe. I realize that the spray zinc is probably a small problem, but that stuff is cumulative.
