"Can't Live Without"
This is the best cleaner I have used yet. I just can't paint without it. Pros- I love Tamiya paints and us them when ever I can. There cleaner is the best. I even us it on my Testors paints. Cons- none. It might be a little high in price, but saves a lot in replacing paint brushes, paint guns and parts.

"The Absolute Best For Tamiya Acrylics"
This is the best thinner possible for Tamiya acrylic paints. There is simply no better option. Yes, mineral spirits also work, but not as well. Using a 0.1mm airbrush tip, the default Tamiya ratio of 2 parts paint for 1 part thinner (this thinner) is perfect. There is no other word for it. It never clogged, sprays smoothly with no spitting, and doesn't run. Of course, I am building up light coats, but even then it is still amazing. My only gripe is how expensive it is compared to alternatives. Thankfully, one bottle of this can mix you 34 cups of 3/4 Tamiya paint at default ratio. That should be more than enough.

"Better than plain alcohol by miles"
sad76 (
When I first started using Tamiya acrylics I wasn't too thrilled, mainly because I was an idiot and tried to thin them with straight IPA, and then a homebrew concoction that I found on some website. Tip drying, bad finish, you name it. I finally broke down and bought this stuff, and the difference was like night and day. No clogging or drying on the needle, and the paint went on like silk. I could complain about the price, but it lasts seemingly forever.

"Tamiya X-20A Acrylic Paint Thinner"
A lot of people think that when airbrushing, there is actually a true ratio of paint to thinner. This is not correct. You thin paint to the consistency that you want. Anyway, this thinner is useful because it can also thin paints along the Model Master acrylic paint line. Tamiya acrylics are easy to handle and use, so if you are using these paints, this product is essential.
