I second that. I have a cartridge of it in a grease gun. The merit of buying a little tube of the stuff is that it fits in your tool box for when you just need a little, as for threads. I use the big stuff for packing wheel bearings. I haven't used ball-bearing bottom brackets or headsets in years, but it's good for them, too.
