Agree with all the other comments, use these all the time. One of the biggest issues is how the color will look once it is dried! What you see in the bottle will dry a bit darker. I also clear coat all my craft paints with Rustoleum 2x clear, Testors Lacquers, or varnish if hand brushing. The results with a clear coat will also differ from the color in the bottle or dried! Whenever I have the airbrush out, I have spoons primed that I then test colors and clear coat for later project ideas. I agree, large plethora of colors and mixing abilities with the craft paints. I also add Future/Pledge to my thinned acrylics before air brushing. Seems to help with durability and tip drying issues (airbrush). All the spoons in the attached image are craft paints, most cleared with the 2x. Definitely give it a try!
