Re: Applying weld-thru primer

And if it's not fully flashed, it will weld like crap! So let it flash off.

I just did a patch this afternoon on my truck, primed it, left it outside while I came in and ate lunch went back out and welded it in. If it were winter and cold, I would have even left it until the next day.

On the respirator, cold rolled, not a big deal. You probably still should, but it's not horrible. But welding on anything made after the late seventies, more and more parts were galvanized, the last 20 years or so EVERY SINGLE part is galvanized, coated in zinc.
