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.
