One thing about vinyl. It's slipery.

If you put a piece of that vinyl around the sleeve (under the rubber 
coupling) it won't stick even if water did get in there.  I like the idea of 
that rubber coupleing. OTOH I don't have any tower top sleeves used as 
bearings.

Never seeze?  The black or copper colored stuff.  Get a little on your hands 
and pretty soon most of your body is the same color.  I think the suff is 
alive and migrates, but it sure does work.
