ok, so for my custom all i have currently is the chest/back/shoulders. All but 1 peice is painted, which that one needs to be resanded and reshaped. I have the material for my vest that Im using, a black Vinyl. Here's some pics of it when i first got it unpainted (photoshopped to reveal the real color it is now) and how it is now, which my flash makes the color look blue instead of dark grey. And yes im using clone trooper hand armor for it, but with different gloves.
and here's it before the grey and inbetween coats of chrome to fix impurities
