[TowerTalk] Mast Coating to Prevent Rust

[Garry Drummond]

I am putting up two 50' wooden poles with a 21' section of 2" galvanized 
water pipe thru bolted to each pole to support a 135' long dipole. The 
galvanized pipe is new and I want to coat it to make sure it doesn't 
rust or discolor over time. I know galvanized pipe shouldn't rust but 
wonder if there is any type of coating I should put on it before 
erecting? Once it's up I won't be able to reach it if attention is needed.

Any suggestions?

Many thanks & 73,
