Use Rustoleum oil based paint you get from Lowes. To make olive drab, mix one quart of rusty metal primer with one quart of hunter green. I use it for everything, wood or metal. Blinds, feeders, shooting benches etc.

Rusty Metal Primer
Hunter Green

I thin it and spray it on with this HVLP sprayer from Northern tool, but you can brush or roll too.
