Thanks Guys!
Marcin, I've rcently bought a set of the life colour paints (German camouflage set) to try, but forgot I had them and resorted to Tamiya paints for this. It was basically a custom mix of varying shades of grey.
Andy, I used the easy ones! I want to use the ones in hundreds of pieces, but unless I'm going to show them disassembled, there's not much point!
Robert, I have kept some in-progress shots, but I can't find them? I'll find them eventually though! I can't remember any specific problems while I was building it though.
Vinnie
