I bought a can of spray latex (yellow, of course), to try out.
Used it on some old .50 ammo cans. Seemed to go on just as well as
regular spray paint, and seems to be holding up as well too. Smelled
better too.

Back when I flew r/c combat, 7-8 years ago, I used spray latex on foam
wings, as solvent based paint would eat the foam. I thought it worked
pretty well then, and would imagine it getting better.
