Mark, I've used alodine (1204 I think, I'll double check). I used it to treat some torx bits that started rusting as well as steel hardware, I don't think it's hard to find but I don't remember where I got my bottle. You do want to clean it real well first and it will give it a flat black finish otherwise it comes out brown.

And my bottle of Alodine 1201 says "Chemical Coating for Aluminum" on it. Right now I have a piece of 4130 out in the sunny front yard that I mist every hour or so. One end is bare, and the other end I waxed with Blue Coral Poly Sealant. That'll be a data point after a few weeks, but so far one end is rusting, and the other looks new...

I have no idea what that does to the weight, or the pocketbook, but the rational behind the zinc plating it that it if the zinc gets scratched, it continues to be effective, since zinc is anodic to steel. If a layer of paint gets scratched, the steel undergoes rapid, localized corrosion. The book also mentions tin plating, saying that it works, but steel is anodic to tin, so if the tin gets scratched, the localized corrosion would be worse than the paint coating. So, disclaimer: I have no experience in this area, just a book.

Hey, I have that book too! Guess I should have opened it. Actually, I'm looking for something I can do at home, but I may have to go that way. I also considered powder painting it, which is supposed to be only .002" thick, but last time I had something coated it looked more like a .100", and had runs all over it. They make home-brew kits, so that might be an idea. But plating is a distinct possibility, assuming they can handle something 8 feet long. Waxing may just get me there too, as long as I inpect it every time the wings are off, and it'll make it operate with less friction. Call me optimistic on this one...
