Herr Zerk must have been the guy who invented the grease nipple I guess
I use Castrol SX2 because we have some at work in tubes that fit the grease gun, it is designed for marine use on exposed cables and gears on deck etc so I figure it should be good for the blunt end of a RIB. I got some of the funny blue stringy Johnson waterproof grease but it comes in silly tubes and is a pain to use so I don't.
