## Customer Reviews

### ⭐⭐⭐⭐⭐ Great DTM product and seller!
*by R***E on September 29, 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!

### ⭐⭐⭐⭐⭐ Very good
*by A***M on April 5, 2025*

Sprays nicely and sands very well

### ⭐⭐⭐⭐⭐ Works great if you know what you are doing
*by A***D on October 18, 2023*

everyone yacking on about it drying too fast needs to learn how to read the weather and humidity the day they plan to use it instead of 4:1 knock it down to 5:1 and reduce a little if you can't figure out how to get it to work for you not discouraging DIY but the Internet is free read up watch some videos there's a lot of info out there about how to do an entire paint job start to finish and the good ones will talk about the effect the weather some gloss over that (no pun intended ) because of you do it regularly you'll just know i use this for customers on a serioud budget and ive had some cars out there for about 2 years now with thid on it i use every product on a vehicle of my own before i put it on a customers vehicle and my truck tail gate and bedside is still flawless 2 years later every paint and primer is different in its own way if you are going to paint you have to learn to adapt to the material you use
