Mast step protection from corrosion


I am noticing some corrosion (rust) on the bottom part of the mast step on my Swan 47. The glassed protective layer has cracked at places.

I've read through the previous threads and there is a lot of info on refurbishing it.

Short of taking it out and rebuilding. Can I protect it by paining it? 

Is the original galvanized steel? If so, can I use epoxy based paint, oil based anti rust (Rust-Oleum 7769) and enamel or something else? 

Any guidance on how to treat and protect rusty parts would be great!

Hi Peter,

could you please post or send me via private message some photos? Originally there is no glass protection.

There is a complete document on how to rebuilt it on classicswan (technical papers).

Looking forward to seein the photos.

All best,

Hi all,

Just a quick update.

I removed as much rust as I could and painted the mast step with cold galvanizing paint. 

Looks much better. Hope it stops or at least slows down rusting.
