I have a black long rifle that I think I may want to get painted. I'm thinking some sort of desert type or even some sort of urban grey type of camo....

How do you do it?
Certain type of paint, etc?
What are your favorite patterns, etc?
The stock is a little "texturized" (B&C MK2 stock), can I paint over that?
Other thoughts I may be missing?

Thank you.
