I agree that a zinc coating would be the ticket. Hot dip, painting with a high zinc coating (95% zinc coatings are available). If you were near me, I would suggest a sprayed on zinc coating (100% zinc metal no carrier)as I have a metal sprayer that applies metal to most any other surfaces. Then overcoat the zinc to what ever you need (be sure you use a covering material that is ok to apply over zinc as some products will not adhere well to a zinc surface.
One thing to be sure of doing on the piece is have a good radius on all of the edges. A sharp edge will NOT accept any sort of coating to the same thickness as a flat surface. Paint, powder coating, metal spray, what ever, a sharp edge will have a very thin coat compared to the flat surfaces.
