I’m cheap, and haven’t airbrushed in awhile, but I’ve used windshield wiper fluid. Like super cheap Windex.

Actually, windshield wiper fluid is an excellent thinner for Model Master Acrylics. I used it for years with great success. It sprays beautifully, lays down perfectly, and no tip dry.

I used to use windshield wiper fluid with the original Polly S acrylics for thinning until they came out with their own airbrush thinner.
