painting milodon oil pan?

^ its gonna be very tricky if even possible to take the paint off with ruining the zinc. they bond together pretty well and using a stripper or something like that will most likely mess it up. your best bet is if you really want the yellow to just strip it all and have it re-zinc and yellow'd. try to find a local plater to do it, if he says more than $50 to do it he's a greedy sob! haha. zinc and yellow is very cheap and easy to do

and billytuffnuts, you can paint right over it no problem. a lot of parts are zinc'd before they get painted for extra protection
