What kind of paint to use and style of painting(feel hand airbrush)?

 I am wanting to paint a full face black Bell motorcycle helmet. Or i want to mod it by adding brittle plastic. any ideas on either one? Thank you. And yes i want to wear it riding.

Airbrushing an acrylic or enamel paint should work - I would stick to water-based because the core of the helmet is a type of styrofoam and some solvents (many solvents) will destroy it.

As for adding plastic - how much adding are we talking about?  you can do anything that doesn't remotely nick the foam core - any damage and the helmet is useless for protection. 
To add things like antlers or minor surface changes I'd recommend something like home-bake sculpey plastic.
