Since I brought up the Tungsten Disulphide a while back, I figured I'd share what I learned.
After doing some more research about Tungsten Disulphide, it appears that it has to either be blasted onto or lapped into the surface to work. The stuff came from NASA and the aerospace companies say you get near permanent lubrication with a .5 micron layer thickness. Apparently, it forms a pretty good bond with the surface once it gets on there.
While I was researching, I found some of the aerospace companies in LA that use the stuff. Dicronite won't even sell WS2 lubricant, they will either apply it for you or license the process.
