    Tamiya X-20A Big Bottle

    You really only need a few drops of this stuff in a typical airbrush cup, so 250ml will last you a very long time. Good thinners - mixes very well and doesn't seperate after a few seconds like a.n.other I've used.

    Thins acrylic paint.

    This stuff is great! When I add (and mix) some to (with) acrylic paint the paint becomes thinner. The more I add the thinner (or more viscose) it gets. Provides more consistent results than water or saliva. If you have some acrylic paint to thin a bottle of Tamiya X-20A is for you.

    Thinner is better......

    I have been modelling aircraft of all sorts for over 30 years, yet I am a relative newcomer to airbrushing techniques. I have used an airbrush before, but it is an art unto itself and after talking to a friend he recommended using a thinning agent to obtain better results. So, being an advocate of Tamiya paints, I chose this one to get me going. At first it is trial and error, but with a little practice correct consistency can be easily achieved. There are other products out there (and I even have friends who use water!), but this is the one for me. Well worth the small outlay, and if properly used, will last a long time.
