I'm building one as well. I have the luxury of working at a Sherwin Williams Commercial and Industrial store and being their Master Blender. I made my own paint. I made mine out of Polane B. I chose RAL 5000 for the ear caps, rangefinder, and cheekbones. And I chose RAL 5015 for the rest of the visor. I'm going to use Rub N Buff for the silver. I just need to figure out how to best get it to the appropriate shine.
