Look in the far right column, at the top, "Sodium Grease" with a 
"Mineral Oil" base, no soap.

Also known as "cup grease".  Sodium grease spec column on this page:

Numerous sites claim it's not good around moisture.  One fellow in an 
antique auto forum states:  "I would avoid it due to its inability to 
survive immersion any waterproof NLGI 2 grease is fine"

I'm finding tons of info on sodium grease, but it seems it only 
available in huge tubs at hundreds of $$$$.

I had some tubes of it in years past from a "constant velocity joint" 
rebuild kit for a 1991 Toyota 4Runner, but it came with the parts.  You 
van be sure I'll be saving any I come across the in the future.

I was in NAPA Auto last year looking for greases for motors, and saw 
some waterproof marine grade bearing greases.  From what I can see 
online, they are NOT the original sodium based, but may be comparable in 
usage.

A search on google for:  Dupont Molykote Grease brings up a lot of hits, 
and switching to images brings up small tubes.  I'd double check all the 
specs, but it looks like there are some promising equivalents out there.
