Joe - The light gray is Testors Camoflage Gray in a spray can (I'm a big believer in easy), the dark gray deck is 50/50 mix Model Masters Panzer Gray / Euro1 Gray, and the upper decks orange is Humbrol #100 Orange in the little tin. Everything was doused with an acrylic wash called "The Detailer". I used black for the grays and rust for the orange. I used Q-Tips dipped in either water or rubbing alcohol to remove most of the wash, leaving it in the recesses. Oh, the paints were enamels.
