Good primer.  Sands well.  Came out dry with my airgunsa and a 1.8 tip.  I bought a tcp spray gun to use for primer and it worked well with a 2.5 tip.  The 2.0 was still a little dry.

### ⭐⭐⭐⭐⭐ 







  
  
    Great DTM product and seller!
  

*by R***E on Reviewed in the United States on 29 September 2024*

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!

    GOOD PRIMER, QUESTIONABLE INSTRUCTIONS
  

*by D***T on Reviewed in the United States on 4 November 2023*

Sprayed this mixed 4:1 with a 2.0 tip at 80 deg, 52% humidity.  Came out almost granular, but stuck well and covered well.  I think the recommendations to use less activator and some reducer are spot-on.  The only downside was the extra work of eliminating the granular bumps with more sanding than you might of had to do.  Don't know how it would have sprayed at 70 or 75 degrees.  At 80 the pot life was definitely shorter than 1 hour.  Clean that spray gun quickly!
