RUST.....any known treatment

[Daifuse]

I have been using a product called 'Fertan' for years now, having tried many others this is the best i have found. It is used by boat yards as rust is a big problem. Not cheap but i am happy with the results.

I used Fertan for years on my narrowboat. Wonderful stuff. Just follow the instructions for the best results. The port authority I worked for would put it in the bilges of the pilot boats which always had water in them. It prevented corrosion even in salt water.
