Rusting Anchor Chain...What to do?

Rust has replaced the galvanized coating of my anchor chain.
Any coating that I can apply to help the situation?
I was considering some rust converter like Naval Jelly or soaking the chain in oil. Half of the 300 ft is affected so swapping the chain end for end would kick the problem down the road for now.

Re: Rusting Anchor Chain...What to do?

The only long term solution to the problem is to have it re-galvanized (make sure they have a centrifuge for chain, not all galvanizers do). You should also check the diameter of the rusted links to see how much steel you have lost. A little rust is no big deal but if you've lost a significant amount of the original diameter it might be time for a new chain. Factoid; one inch of steel will make seven inches of rust +/-.

You will almost certainly find that it is not economic to have the chain regalvenised. Sand blasting and the regalvenising charge will equal or exceed the price of new chain.
