[TowerTalk] Anodized Aluminum Tower

[Don Havlicek]

The electrolysis is internal to the tower legs.
If you remove a tower bolt, you will find it is no longer cylindrical in 
shape, but may even look 'coke-bottle' shaped from degredation.
On my Universal towers, I coat the bolts with silicone seal before 
assembly/insertion in the tower legs to minimize damage.
Worst case condition I had was when one bolt simply became two pieces 
over a 20-year period of time.  Guess I missed getting the silicone seal 
on that one.
