Review: The best weld through primer I've worked with. - For plug welded overlapping seams I apply two thin coats to both sides, let dry a half hour, fit the joint, scrape away the primer in the plug weld hole (I use a ground down drill bit of similar size), and then MIG weld with no splatter. I prefer the zinc vs copper version of this product. I find the copper version to produce more splatter and porous welds.

A: Yes, but TIG welding requires sustained heat as opposed to spot welding.  Weld through primers work best with spot welding.
