I've done something similar to what Larry has done; however, I use heavy
duty, flexible vinyl and fold it into a simple cone.  I wrap the top of
the cone around the mast above the thrust bearing so it forms an
umbrella to protect moisture from settling on or into the bearing.  The
vinyl can obtained as scrap from fabric shops or upholstery shops.

Even easier is to use truck or car inner tube. Cut it so it drapes over the top of the bearing. Secure it to the top of the mast with a hose clamp.

Another trick, although the mechanical purists might not approve, is to
pump grease into the thrust bearing until it comes out of the housing.

If your bearing has a Zerx grease fitting(sp?) mine did, this is what you are supposed to do. It purges water and ensures everything is properly lubricated. I used a good quality all temp grease.

The bearing didn't fail, the tower leg did YMMV :-)
