Very good weld-thru primer.
Used to treat flange welds. Good coverage and quick dry time. Bit steep on cost but, I wanted to do it right. 3M Automotive products are always great quality.

Good for body work
Used this to protect sheetmetal from rust on the inside of a body repair. I couldnt access the back side of the patch once it was welded in. This stuff is expensive but, it protects the metal during and after welding.

Useless, it bubbles out of the neck of the can and pours all over the floor.
Useless, it bubbles out of the neck of the can and pours all over the floor. It didn't spray at all. The can is still full. Thanks for that, i don't appreciate wasting money.

works just as it should
used to cover metal parts that would not be able to paint after welding, keeps rust away, welds thru just fine, was able to wipe away weld spatter, of which there was plenty from using HF flux core welder, welds holding just fine

Worked well but expensive
Worked well. Pricey but worth investing in since it should keep things from dusting a bit longer than without it.

Yes worth it!
decent product- 2x the price of the other brands for a reason.

Absolute JUNK
Like everyone else, the can I bought was absolute junk. Sprayed out from under the nozzle all over me, the floor and everything around what I wanted to spray. Makes it very splotchy. Of course, no returns so I'm SOL.Avoid this, especially at this price!
