## Questions & Answers

**Q: Is this recommended for car rims? I've never used an airbrush before**
A: Airbrushes are for painting small areas. I use mine to paint models. The reservoir on the airbrush doesn't hold enough paint to do large surfaces. I wouldn't think this is a good fit for what you want to do. Sorry.

**Q: Are the threads on the grex airbrush npt or bsp?  i want quick connect it to my 1/4 “ npt compressor**
A: npt

**Q: I have been using a co2 cylinder instead of a compressor with an old testors airbrush.  would the grex be compatible with the co2 cylinder?**
A: Yes you would just need the proper hose and fittings

**Q: Grex tritium.tg3 vs gsi creos mr. procon boy wa trigger review?**
A: I got the GSI Creos before I started using the Grex. I find the Grex easier to use during long spray sessions. Simply because it's bigger with the handle. The GSI Creos doesn't have it. Also, the Creos is a much smaller airbrush. It also has a much larger needle - .5  the Grex has a .3

## Customer Reviews

### ⭐⭐⭐⭐⭐ Reliable and easy to use!
*by R***L on July 8, 2025*

A+ airbrush, been using for 6 years now.

### ⭐⭐⭐⭐⭐ Puts a lot of paint down
*by L***O on June 13, 2020*

The feel of this airbrush is natural. The trigger pull is outstanding, it is easy to go to pencil lined or lots of paint by the pull of the trigger.I'm thinking I have a small air leak in the gun but it doesn't affect the performance.I've had issues with orange peel finishes with other airbrushes, it could have been the thinner I was using but I was never satisfied with the finish. This airbrush right out of the box worked flawlessly and my DIY thinner did wonders.So far it has been easy to clean and it has been a joy to work with.I can't say enough about the trigger mechanism it works flawlessly and doesn't cause fatigue by having to have your hand in an unnatural position to spray.I had one jam of the needle but a Q-tip with thinner solved the issue right away and I was able to continue spraying with a minor stoppage of spraying. With other brushes, I've had to stop numerous times and on occasion clean them before I could continue spraying. Like I say it could be my DIY thinner helping to eliminate my issues but when I had a good mix before I was continuously stopping to clean the needle from built-up paint on the nozzle.I've not had to take it apart to clean.I'd say if you are looking for an airbrush get this one it works great.

### ⭐⭐⭐⭐⭐ Perfection in Airbrush!
*by D***S on August 11, 2019*

Grex makes the best of the best airbrushes. I have been using the previous XT version for many years until this new TRITIUM TG3 came out. It is perfection!!! It has been greatly improved to be the best one can buy. The cup is a top feed (instead of side feed in the previous XT version) so this improved version sprays and cleans with greater ease. The major advancement is the interchangeable needle sizes. It comes with a .3mm. I have bought all of the others (.2mm for very fine detail, .5mm for medium work and the .7mm for heavy more viscous liquids that are nearly impossible to spray through other airbrushes). There is presently a resurgence of hand made art and illustrations in the digital age and for the airbrush artist/illustrator, the Grex Tritium TG3 is perfection!
