ok so I bought the chefmaster gel-based icing colors, does anyone know if you can water them down and use them in an airbrush?

Well, not really. Airbrushes really do need airbrush color that is the correct consistency and there's no chance of even a tiny lump.

i have had an airbrush for 12 years.. i have never used anything in it but airbrush colors.. i clean it after each use..never had the first problem with it.. it is a KopyKake, airmaster...

Thanks ladies I appreciate the input!
