Custom Shop - Black Epoxy Primer/Sealer 2.1 VOC (2-Gallon Kit) Anti-Corrosive DTM High-Performance Primer for Automotive and Industrial use Kit= 1 Gal. Epoxy Primer +1 Gal. Epoxy Hardener (1-1 Mix)

Yes it come with a hard black ball in it, that’s pretty typical. And a paint shaker doesn’t work well, get your paint stick out and start stabbing and poking, it will eventually dissolve and it will stay mixed or easy to mix up with a stir or two. It sands nice and hard like you want, and gave a great seal and starting point for my finish paint. I did add a little black tint for a less see through finish and highly advise, it will make it longer to cure but works well. It’s a very high quality primer at a great price point.

needed a small amount of epoxy primer for a project and this stuff was great. It is well worth the money. The finish came out great. It sprayed and laid very nice with a good amount of coverage.

After reading other reviews I was worried about mixing. It took about 10 minutes to mix but it sprays well and flows smooth. I would buy again.

I've been a huge fan of Custom Shop products for some time now, as I've ordered many times from TCP Global. However, this last batch of primer was extraordinarily difficult to use. The solids just would not mix. I used a drill-attached mixer, I took the can do a paint shop to have them mix it in a machine, and there was still solids at the bottom of the can that would not mix. Additional mixing with a drill attachment after having the can shaken did not help get the last significant chunks of solids to mix. Shooting the primer like this gave me a highly glossy finish (more resin, less solids), which was a royal pain to sand down. Upon contacting the seller, they assured the solids in the can were normal, and that it would mix, but was not the case. Upon looking at reviews again, this looks to be the case for a few other buyers here as well. I'm fairly certain I got a bad can of primer. Additionally, one of the two cans I received was dented, so it was VERY difficult to close the lid and create a proper seal after opening it. I'll be making the jump to Speedokote for my next batch of primer.

Great product, you must mix it well like any paint system. Smooth flow out, used my Sata 1000B with a 1.3mm needle at 28psi. Put one medium coat on and I can still shoot one more. Great mileage from one gallon @1:1

Works real well, good hard primer. But dries a bit slower then other primers ive used. I did the 50/50 mix ratio recommended. I do recommend it for the price and quality though.

Great primer. Very good adhesion

Just what I needed
