A (not full scale) Normandy is... in the works. I'd rather not talk about it too much until its more than just a pile of blueprints and styrene, but I'm sure I'll be firing up a thread on it in the next few months.
THAT is a solid pain, actually. Its three different layers of paint, but its the best way I've been able to replicate gunmetal accurately without buying some specialty paint.
The first coat is actually an ACE hardware store brand silver that comes out like brushed chrome. I actually lucked out, and there were 4 cans of this stuff at my office that were being thrown out last week, so I snagged them. More free supplies! Normally I don't like to use anything but Krylon paints, since the humidity here in GA can play hell with some spraypaints and Krylon is the only stuff I've found that doesn't get borked when its really humid outside... Can't argue with free, though.
This is a crummy iPhone shot, but you get the idea:
After that, I mist the layer with Rustoleum hammered dark silver. to do this, you have to hold the can about 2 feet away from what you're spraying so the paint hits the surface in small clumps. This tones the chrome down. Getting this part even is a solid nightmare, but luckily the M8 is pretty decently weathered.
After this coat is on, but before it dries (within 15 minutes) clearcoat the entire piece in Satin. I like to use Krylon. I did this same process for the "metal" pieces on the AER9.
The final finish on the M8 won't be as dirty, but you get the idea.
I'm going to have to make another purchase... plasti-dip. In doing research, this seems like the best way to get the rubbery effect with the least chance of it chipping, scratching, or cracking. Hopefully I can try out some tests tonight.
This will bring my total up to around $16. I had to buy another can of primer and those little hex screws too.
Damn!
