Yes...there's a BUTT plate. Get all your giggles out now, folks. (And if you thought that was funny, there's also a CROTCH STRAP.)
Here are the pieces painted silver (Rusto Aluminum) with liquid mask added for the macro damage.
Next up, the under-layer of Rusto Line Striping Yellow:
Another layer of liquid mask and the final color, Rusto Hunt Club Green misted with flat black. Once that dried, I scratched the pieces up with a screwdriver and some gravel. Finally, a coating of Testor's Dullcoat.
To attach these to the costume, I was originally going to use a belt, but I decided to use the same grommet method I used for the flak vest. There are enough belts on this costume already!
So I added #8-32 1/2" screws to the backs of each piece, with an extra screw for the crotch strap.
Grommets added to the pants:
Here they are, all finished, and on the mannequin!
And with all the belts and straps!
