Review: Good product - Durable and easy to spray for a beginner. Adheres well to properly prepped surfaces and has a smooth finish with reducer. Sprayed in a garage during a Texas summer
Review: Great product. People who complain aren’t familiar with it. - 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.

### ⭐ Could not fully mix - Stubborn solids
*by A***N on 29 November 2023*

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.
