I hope someone on this reflector will be able to help me.
Problem:  How to inhibit corrosion of Rohn 25G steel tower in salt water 

Hi John,
 Here's an unconventional treatment that may or may not be of some use. 
Bear with me as I brainstorm out loud.
 It sounds like the salt accumulation is very substantial at your QTH. 
Another approach would be to figure out how to remove the salt on a 
regular basis.
 Assuming you have a source of pressurized fresh water on the island, 
you could plumb a water line up the tower and connect to spray nozzles 
that would rinse your tower, and possibly even the antennas. 

Beats replacing it every 5 years. And all done from the ground. With a 
solenoid valve arrangement, you could select one nozzle at a time for 
max spray pressure, and to provide a sequence of spray from top to 
bottom, following gravity.
 You could have a single nozzle spraying up at the antenna and rotate 
the antenna through the spray for complete wash.
 Follow up with antiperspirant and some foo-foo, and your tower is ready 
for action! <*grin*>. A shave might be a litle more challenging...

 This in conjunction with a suitable coating could give you much more 
tower life.
 OK, just an idea to spur other solutions.
