Thanks Andy and Rowan !
Andy - I mixed RLM 66 (black gray) with flat black for the "black" areas. I wanted a shade that looked almost black, but would show a pure black wash. I used a few different variations between the seats, instruments, and consoles. If you look at something that's actually painted black, the shadows will always be darker. I try to replicate this on my builds.
I will be painting the camo the same way I did this 1/48 Hasegawa Scooter - freehand:

Rowan - the metallic details were done with Model Master Metalizer non-buffing Aluminum and Steel. It's mixed and intended to be "airbrush only," but small areas can be painted with no ill effects. The metal particles are reasonably fine, and don't look like large "flakes" in the photos. If these paints aren't available on your side of "the Pond," you can mix a touch of white, black, or gray with a good-quality chrome silver. Chrome shades usually have finer particles than other "brush-friendly" metallic paints.
As for building out of our "comfort zones," I think it has somethiong to do with the Earth's magnetic field. Right now, I know of half a dozen or more modelers who are building things they normally would never consider. I'm building this one because I'm getting paid to build it. I'll never build for the frivolity of a dare.
Thanks again !
