Works great to thin Tamiya paints for airbrushing. Since I do not hand brush Tamiya paints, I open a new bottle and fill it all the way up with this thinner then shake the heck out of it. Now I have pre-thinned paint that can pour directly into my airbrush.

This also cleans Tamiya paints out of your brushes if you do hand brush them. I also use it to clean my airbrush after done airbrushing Tamiya paints. I fill the airbrush cup with clean thinner and stray it at high psi. Works great.
