The weathering looks great on those. The clean one's a tad too stark clean, although I'm not sure what you painted and what you didn't. (I'm a GI Joe "ARAH FAG" who is slowly getting into the non-Hasbro vehicle world.)
I have yet to paint a vehicle, though. So one of these days I'll tackle some Humvees and hopefully some others. Yours look great. Can you give us a quick rundown of the work you did to them?
(Others like NSA and KT will already know from experience, this is for the dolts like myself.)
