I have been waiting this thread out to see what options people are using.  

I like to use a product called SuperLube that I get at the gun store.   It's synthetic and I find it doesn't like to pickup dust like other types of lube.  It works great on an AR-15, marine fish tank light fan bearing, and on disk drive rails.  Basically all extreme environment uses involving carbon, dirt, dust and salt water.    

SuperLube is available in a tube and isn't very expensive like whale sperm, I mean oil.
