I'd be worried about rust inside of the tower legs.  If the environment is that bad and you've battled rust on the outside, then surely there's rust forming inside of the legs.  How old is the tower?  You may wish to replace the top section if not the entire unit.  Every tower has a useable service life and depending on the conditions eventually needs to be replaced.
