## Description

Product description

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.
Review: Great primer. Will use again - 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.
