Or you just buy an aluminum replacement so you don't rip your hair out in another 5-10 years.Before it was installed it, I would strip the pan, apply a chromated epoxy primer, and then either have it powder coated or I'd at least apply a good polyurethane topcoat. Imron Elite Single Stage is pretty durable.
I know that seems like a lot of trouble, but I'd want to make the new one as rust resistant as possible before I installed it.
