Clear coating waterproofing aluminum

I am using a standard range of 2 mil aluminum sheeting. I need a clear lacquer or coating to totally seal it against corrosive salts. Is there any suggestions as to the best methods?

Nycote [adv: Nycote on eBay] is a product that I have used on Aluminum. It stops any tarnishing.
