Q for Weekly show: How to use air brushing makeup on actors

[Bikermouse]

I have been told many times Air Brushed makeup is faster and better than any other type these days. I know this means after you have the little spray machine.

I am wondering if you can anwer or do a tutorial on Air Brush Makeup. Id like to see it cover using a premade machine if possible (since i know someone who can get one) and how to make one cheap if someone cant get one.

Thanks!
