Correct grease to stop corrosion

[mulligan]

Dear all,

I have recently had my mast Awl griped and now have to replace the track etc, unfortunatly due to the screws being St/St I have been advised to use a grease to stop a electrolythic reaction between metals, can anyone advise please as I am keen to minamise any corrosion.

Regards

You haven't said but I assume your mast is Aluminium; the stuff to use on the screws is Duralac, which is a yellow paste containing zinc bromate(or is it bromide? I forget). This will reduce the reaction between the mast and the screws.

I think that I would be looking to use lanolin in that situation.

David,

You are correct, the mast is aluminium and the product you mention sound familiar, have you any idea where I might get this?

Most boatyards and rigging shops will have it, and some chandlers.

You will get Duralac, zinc chromite paste by post from [www.zsparsuk.com=link]here[/url]

A small tube will last for a long time. It is relatively inexpensive.
