[TowerTalk] FW: Rust & paint

[Bill]

I have used both, and for me in the salt atmosphere I live in, the 
Rustoleum Cold Galvanizing seems to work better. I used the reformer on 
outdoor furniture and rust came through the paint. I used the cold 
galvanizing on tower sections, and after two years it looks gray with no 
rust showing through. It lo0oks the same as when I put it on.
