In the mid 90s I went in with a couple of guys and bought 400 feet of used Rohn
45 that had been an AM transmit antenna. It was painted red/orange and white.
The paint was old enough that it was faded and chalky. I took my 100' share of
sections pressure washed them, wire brushed a few spots and brush painted them
with ZRC cold galvanizing right over any old paint that stuck to the tower
after pressure washing. It came out a nice battleship gray that blended in
well with the woods.
That tower is now at its second QTH. No rust, no chips, and it hasn't been
repainted since. The ZRC is good stuff. If you pull a rope over a tower rung
it will actually polish the cold galvanizing to a nice metallic sheen. At the
rate its going I might even get a 3rd QTH/decade out of it.
The only downside that I can see is that you can't get the ZRC down inside the
tubes like a hot dip galvanizing would do.
