Seymour20-1672 PBE Professional Primer, Sandable Black

If you are a weekend warrior and doing a little body work at a time it is difficult to grab your spray gun and go through the hassle of measuring/mixing primer, and then cleaning up the mess. I have tried several products from the "Box" stores and all of them are "garbage". Many of them don't spray well, all of them sand poorly.Seymour Professional Primer is awesome. It lays down correctly, builds nicely, sands easily just as advertised.I wish I had tried this earlier - what a time saver.

I’m not crazy about the spray nozzle as it comes out heavy. Also be careful removing the lid. I knocked off the spray tip and made a mess reinstalling. But at half the price of the big brand, I’ll gladly deal with these nuisances. I can’t tell a difference between this and 3M (other than I get a larger can for about half the price).

.....is that Amazon won't take a return. When you click "Return" it comes up "Ineligible to return". Had the same thing when Amazon sent me a bottle of sunscreen with a proprietary top nozzle smashed. No return! Truly horrible. Amazing needs to fix this. In the interim, if you are buying from this supplier, read only the description at the top, as the photo you select does NOT match what you get.

Update: I think this might be my fault, the wheels although painted in a warm garage may have been too cold. After stripping all of the primer off again, I felt the wheel spokes and they were cold to the touch so it possibly could have caused the cracking. I am going to order more of this primer and make sure wheels are warm before painting as I hate to give a bad review due to my ignorance, I'll update again once I try more.This was two days working on this wheel, first wheel came out great, only difference was the primer I used. Initially the cracking was isolated to small areas so I thought there was oil or a cantaminatiin in my isopropyl alcohol, so I started again, still small areas of cracking after applying primer. Sand prep and repaint, again more cracking, again different areas and small. Trying to change up little things. Finally got the wheel looking good and applied what I thought would be one final coat, but as you can see the primer cracked all over. Finally I realized it was the primer that was the problem.Just putting this out there, I don't write reviews often. I know how to paint and how to prep. I probably just got a couple bad cans.Painted in a clean heated garage.Time to start all over with another primer, ugh!

Directions on can are generic garbage, but the can contents are not. Works wonderfully if applied in one or two light coats. Comes out of the can really fast/heavy, so be careful. Welds well and does not off-gas terribly bad. It seems to become harder and better adhered to the metal _after_ welding (heating) than before. The sample I TIG welded was 22-ga mild-steel sheet metal, though it would work fine with any process.

Hard to say how well it works as you can't see in the joint you just welded. But as far as I can tell there is nothing between factory joints so this has to be an improvement. You can't start the weld on this alone. You have to start the arc on bare metal first then move across this. I'll have to come back in 50 years to see how it compares to a factory joint :)

Im sure its great stuff but as my cans came with no nozzle and the piece of the old nozzle was broken off inside i never got to use it. I guess the head nozzle installer was out with covid that day. Tried to remove the broken piece so i could put a nozzle from a different paint can in it but uuhh..yeah... didn't go well. Primer started spraying all over the place and wouldn't stop so i threw it in the woods. Ill go collect it later once its empty and throw them both out! Thanks for nothing!!!!!

This stuff is phenomenal! I've gone through about 8 cans of it so far on a large welding project and it had worked well beyond all expectations. I find it goes on extremely well with a nice fan spray nozzle. It dries quickly and allows a predictable arc strike and nice clean weld bead when welding through it. Once welded, there is nearly zero material that comes off around the weld. Really amazing stuff and a must for large projects where you you need to coat hidden areas during assembly before welding.My only regret is not ordering more of it earlier. I had to resort to a local off the shelf product for my project that was absolutely terrible for about the same price. It nearly ruined my project. Needless to say, I am back on here now to order a bunch more to stock my shelf in the garage.
