Tony:
if you have only rust spots in the upper sections,
maybe caused by guano , you can clean the spots of
rust apply the Brite zinc or other cold ganvanizing
spray and later put some rustoleum over to prevent
more rust.
is the thing i will do in my tower if the problem is
just rust spots, my area is very dry and hot , this
will resist very well
