Painting Rubber, Need flexibility.



Hey Guys, I'm full of questions. Here is another;

What is the best type of paint to use in the airbrush for painting on rubber that is constantly flexed? I have read that one of the major things to make sure flexibility is to spray light coats, other than that is there a paint that is better than any other in the flexibility department?

Want to paint the rubber outsole of a sneaker.
