While it would take *many years* for an uncoated piece of steel to
oxidize sufficiently to affect it's structural strength, it's still a good
idea. Besides, the rust running down the tower makes ungly stains and may
cause acceleration of other tower hardware rusting.

Try a marine paint - available just about everywhere and you can brush
it on. Same with an idustrial coating. Look in the yellow pages under
industrial coatings or a related heading; maybe they can recommend something
else.
I've tried the Hammerite and it didn't adhere very well and just
flaked off. Prep is important - wash the mast off with TSP and then paint
away.
High quality spray cold galvanizing paint like LPS or Klein has great
adhesion. Champion has the Klein.
