Works great
I use the weld through primer when I gave body sheet metal that will be welded together with plug welds. It's just extra insurance against rust through of the new panels in years to come. Though I no longer work professionally, when I did, SEM products never let me down. Price wise, it's sort of middle of the road, but I don't trust using the less expensive brands that contain a smaller percentage of the rust proofing ingredients and have less electrical conductivity which makes getting a good weld more difficult.

I still had to sand the product off since it didnt want to wed through
I guess it works good for rust and all but i had a realy hard time welding over the primer ..so i ended removing the primer in the areas i was going to weld . So i guess it defeated the purpose of the weld through primer .

Exactly as youd find at the auto part/paint store
works as listed by the manufacturer had a bad spray tip which can easily be dealt by taking one from and empty can and simply applying it in its place. other then that great product to the exact manufactures specs etc will order again in the future

Great weld through primer
What is nicely and dries quickly. Easily weldable and looks good. I just wish it was black.
