Older aircraft (those of the so called "rag and tube" construction) had a 
fabric covering over a welded steel tube frame.  The tubing was filled with 
hot linseed oil and let set for a while before draining.  Drain holes were 
strategicely located.  This treatment worked for many years

I did something similar with the mast that goes up through the center of my 
tower.  I capped the ends and then poured in a thinned mix of Rustoleum (TM) 
primer. I let this set for a few minutes, then poured it out and let dry for 
a day or two before repeating the treatment.  It did eliminate the rotator 
getting covered with rust stains, however this is a preventative aid and not 
a cure all.  It may retard the formation of rust, but I doubt it would 
prevent it.

Galvanizing would be better and on top of that making sure the tower legs 
can drain. Typically tower legs that rust through fail due to some 
obstruction that causes water to accumulate in sensitive areas.  Even "Mud 
Dobbers" building a nest could do it.
