That's the stuff that I asked about around a month or so ago. I talked to the guy that was selling it on the Pirate board. I asked him some questions about using it throughout the 80 series including the birfs. He contacted the makers and was told that it is designed for slow bearing use, ie. birfs, high speed bearings, wheel bearings and one of it's principle designs was for slip joint uses on agricultural/construction equipment. So, yeah as soon as I get a chance, I'm ordering some and doing the whole shebang including the front axle. There was a guy on the Pirate board that works for a company that has used the stuff for years and he said that they have a tough time washing the stuff off with pressure washers when they clean up their equipment. He highly recommended the stuff as well as several other PBB users.
