A company I used to work for used a "Hard Anodizing Process" for Aluminium
transfer chutes in the food industry, this lasted pretty much for ever
exposed to all sorts of chemicals, solvents and water. It was not a cheap
process though.

Actually they have figured it out. The chromate conversion coating
process makes aluminum corrosion proof even in a high temperature salt
spray environment, and the coating is highly conductive. It's widely
used in the aircraft industry but may not be practical for radials.
