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.

Absolutely the best stuff on the market
Far, far better than 3M. Better than SEM. POR-15. It's the best stuff I have ever used. Just remember it's not really weld through, it more like weld next to primer. Clean the spot you intend to weld.

Weld through primer
Bought this for plug welding sheetmetal, i had to scratch the paint to start the welder but otherwise it did what it was supposed to do.

Best of the best
It’s expensive, you know why ? Because it’s worth it.Good coverage, survives welding pretty good. I’ve used it on new exhaust pipes and it’s still rust free after years of being used.

Ease of use
By far the best weld-thru zinc primer I've ever tried. This stuff doesn't have the spatter or burn back issues like a couple of the other popular brands I've used.

Worked OK
The upol copper with zinc weld through primer bonded and conducted better than this zinc rich primer.

Much better than 3M Weld thru primer.
Originally purchased 3M Weld thru primer and had nothing but problems with bad conductivity and spatter. Purchased this because it was Prime shipping and needed it fast. It lays down very well and welds with no noticeable spatter. Make sure to invert can to clean tip after using, it wastes a little primer but will keep from clogging.
