If I were to paint a tank, I'd paint it black or silver. I don't think they were painted by GM, but plated with something. I've recently bought the black version of RP-342 which is supposed to be Cosmoline and work really well for keeping rust away, so I'd probably use that as a final layer.... maybe get the regular amber color if I used silver paint.
If you don't have the plastic shield anymore, you might check a salvage yard for one.
