Finished up a helmet for a client a few weeks ago. It was a Lexan plastic mask - a bit tougher to get the paint to adhere properly, but I picked up some Faskolor at the Hobby Shop in Mahopac, NY. Great place - the staff was very helpful! Here are a few pics: I have to say, it was awesome to dust off the airbrush again and do a little painting! Hopefully I'll get more opportunities to do so soon!
