I used to use Lubrimatic Marine Grease but kind of ended up disliking it. It worked well enough, but the oil tends to separate out from the soap after a while. I used to keep it in a grease gun, and every time I used it, the next day there'd be a little green pool of oil under the nozzle--oil that should be lubricating your bearings, not messing up your toolbox. I have not seen that happen with other greases I've tried like Finish Line or Park.
