Contains an additive which results in less smoke and electrode wear when welding, and cuts faster than 100-Percent zinc rich coatings.

Impossible to get a decent weld using this “weld through” primer. Using mig process on 16 ga clean steel.Nothing but porosity and poor weld starts.Set up same weld without primer and no issues.Edit: there is a technique described by Caswell, where the primer is removed from the bottom of a plug weld using a small end mill or cartridge primer pocket cleaner. This allows a clean start without sputtering and excessive inclusions.

This is good galvanized primer. It covers well and dries quickly. Used this on some car body panels that were overlapped to keep the rust at bay. Also used it on some panels that were spot welded and it worked well on those as well. You might have to play with the settings on your welder because I found it needed to be hotter to get a solid weld. Be careful on thin panels of course. All total I have bought 3 cans of this for different uses and if I need more, this is the brand I would buy.

The product in sense of idea is great. However when it comes to actuality and real world use it’s useless. My agent who had to weld 3 specific parts on had to remove all the “primer”.The issue being it causes flaws in the weld.Based upon I advise skipping this product.So use at one’s own risk.

I like how it matches the factory primer. Welded pretty good in my opinion. I used a mig welded when welding the panel.

I won't ever buy the $40 3M weld-thru spray primer again, after using this product. Less than half the cost, and does the exact same thing.
