I saw on a Velocity tv show a guy was repairing those pesky holes in the body panels from old school dent repairs by brazing them. Is this better than mig or not?
If you have a section of any body panel that has rust holes I would replace the panel or the whole area that has the holes.......if you have holes in a certain area it is sure bet that the rest of that section of the panel (if not the whole panel) is also rusting very badly.
Heat is your enemy when it comes to sheet metal. I've seen people use lead but never seen people braze sheet metal. I would say mig.
The seams on old mopars are leaded. There are videos of putting lead on cars on youtube.Isnt lead dangerous to heat up? How do they do that never seen it done.

But, actually brazing was common back then, even to replace qtr panelsYeah, I did dangerous stuff back in the 60's & 70's myself..........
Wire feed is going to be cooler for the sheet metal. Move around as not to concentrate too much heat in one spot. I've used a block of copper or brass behind the hole and tack the hole shut. The steel won't stick to the copper, so keep moving it from one hole to the next. When you get real good, you won't even need a block. Clean metal is the key...
Best hole trick I have seen is to take a nail, put the head of it in the hole, with the pointed end out , so you have something to hold on to. wire weld it into the hole. Snip off the pointed end and grind down flush. No globs of metal on the inside..............................MO
I would not use a galvanized nail. Use a size that most nearly fits the hole size. The idea is to have less hole to fill in. Yes , the long end can be held in place with pliers, or use welding gloves . Once the nail is tacked into place, it is not necessary to hold onto the nail.............................................MOAny particular type of nail? Do you hold the long end with pliers while welding?
