I am soon to be a first time user, and would appreciate any tips. But, I primarily need to know is whether the .7 ounce bottles of the coloring are concentrated; that is, will I dilute, and if so, with what? I have not purchased the stuff yet (from Amazon.com), and I want to be sure that it is the right product for me.
The Americolor airbrush colors are a liquid, to be used as is. You don't have to dilute them.
I also use them all the time for painting.
This is the Americolor representative at Cake Central. Maybe you can PM him.
