RE: Painting My Bulldog FOR TEH SHORT TERM
A suggestion for regular paint, with pigment, I would say: Krylon Olive Drab!
Works great and you can spray it on right over the original HL paint, no primer needed. That's what I used for the Snow Leopard.
I think too much emphasis is placed on having a tank with a crew visible on the exterior. For most situations (i.e., being driven), I think the tank should be 'buttoned up'.
