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.

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.James Watts

Hi there Lee,
You should look at Sharkhide 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.
