When I first was licensed I lived in Bethlehem, PA, a steel town.  I had a 
60 ft tower on top of our warehouse with VHF/UHF antennas.  After the first 
year I had rotor problems or so I thought.  I was the thrust bearing loaded 
up with red and black dust from the steel company that had harden.
At first I thought about lubing the bearing but that would only attract more 
dust.  So I added a CV (constant velocity) boot over top to prevent dust and 
water from entering the bearing.
This worked and I never had problems again even after adding a tri band 
yagi.  It also eliminated the problem with water freezing in the bearing.
My choice was out of necessity and was a fix for a problem.  This may have 
been a very unique situation due to our location 2 blocks from the Open 
Hearth,Blast furnaces and cinder plant.
