Sealing New Anodised Aluminum

We just took delivery of two new bed plates (anodised cast aluminium) for our anchor winches on a yacht. The reason they were replaced was there was bad pitting/white oxidation in the anodised surface of the aluminium, I think caused by a originally imperfect anodising job and the harsh salty environment.
As the bed plates are new, I would like keep them looking new and to use some kind of wax to protect them against the elements & Salt. Does such a product exist? we are located in France so some general purpose thing that would be used on car wheels would be great.
Thanks
Lee

I would look at using a Carnuba based wax as it is a hard wax and not hold dirt and salt spray as much as a normal car wax might.

Hi there Lee,
You should look at Sharkhide ⇦ on eBay or Amazon [affil link] Metal Protectant. This product is used quite extensively in the marine industry to prevent such problems. Depending on a few variables, it's not uncommon to get a few years of protection between coats.
