I recently bought a 1973 M35A2, it runs great but needs some moderate body work. I can do most of the sheet metal work my self but I do not know how or what to paint the truck with. Can anyone point me in the right direction for buying OD paint? I have noticed that there are many shades of OD paint. I belieive the different shades of color were related to either the theater of war a vehicle was assigned or maybe the time period. Can anyone clear that for me as well? Thank you from your newest member!
