This product worked very well in my garage

ive used this primer once and i love it. I used it on a 90 degree day, using a hvlp harbor freight spray gun, i sprayed at 30psi to the tip and used a 1.7mm needle and tip. the primer was drying before it even hit the car ( due to the 90 degree temp). But even then, it still stuck and created a nice layer of primer. After sanding with 600 grit to get the texture feel out of the primer, it still covered the car and sanded very nicely. Next coat will be sprayed with a 2.0mm tip and needle to help prevent the paint from drying before it hits the car.

Like thickness, and stretched it further by needing to add additional reducer. Comes with hardener. But at 4:1:1, you’ll need a 3.0 tip and 50psi just to shoot. I doubled up on reducer and with 2.0 tip @25psi, and almost wide open, 80*, shoots flat, and a few thin coats, build up is great and good adhesion. You need to work out what’s best for you. There are better filler primers, but this is consistent.

Sprays nicely and sands very well

This DTM-B624 Primer worked great and stuck to all surfaces on my 1967 Camaro. It also took base coat really well. The product is great, but the tech support is even better! I called and asked questions multiple times and they were excellent customer service. It was my first full car paint job and I asked basic questions, but they more than wanted the help. I highly reccomend Restoration Shop DTM-B624 primer if you have some sand through and exposed metal, but even more so I reccomend TCP Global Corp and their great customer service!
