Thanks ..
I actually painted this one a few years ago, but still have the spray cans around. I used Krylon colors mostly, with mists of different ones to generate the colors I was looking for. Then added the 'damage' by hand with blacks, greys and silvers .... I'll see if I can find the actual colors.
Also ... there are lights (blinking LED's) in the rangefinder and a fan in the helmet which are turned off/on by a bank on two switches (top of inside helmet pic).
