My husband just bought me an air brush for cakes. Yay!
But he didn't get a kit with colors so I ordered some from GSA... I only bought the sheen colors though, and I haven't tried them yet. My first question is, do I have to use special air brush colors or can I use Americolor gel paste with a little vodka or something mixed in?
Also, I'd take any tips you would share!
Thanks!

I would only use aribrush colors. I read of people clogging their brushes with diluted gel colors.

youll need to get airbrush colours. but while your waiting for them to arrive practise on newspaper spraying just water through it.
