I can think of several reasons not to apply coatings-it traps moisture in the interior of the wire, and makes it difficult to see surface corrosion are two big ones.  If the wires were properly galvanized at the time of manufacture, I'd think coatings would be unnecessary.  My $0.02.

In '06, drove out to a site to do routine maintenance.. found a guy on 
the ground. It was the 900' guy on a 980' tower. That led to quite a 
worrisome two weeks, to get the needed materials and someone to install. 
There had been a "bulge" about 50' out from the tower. Seems moisture 
caused corrosion in the core of the cable. Despite my warnings, it was 
ignored until it failed. Luckily, it all worked out, no one was injured 
or hurt, the tower stayed up.

But, I'm no longer involed with that station group.
