What's interesting is their marketing says:
"Sailkote is typically five times as effective, and lasts much longer than, wax, oil or Teflon® based lubricants."
Yet the fluoropolymer is either Teflon or the same stuff.
There are lots of Fluoropolymers other than Teflon (PTFE.) ...
This video states Sailkote is formulated with Krytox, which is Perfluoropolyether (PFPE)...
I'm not familiar with Sailkote, but that would explain why it works well, and why it is expensive. But Krytox is a liquid, so it's not a true dry lube. Still, it doesn't attract dirt, so I guess it can sail by with the claim.
As for using it on tight pliers joints, I'm sure it would work, but I wouldn't use it right away. For tight pliers joints, I wash any oils out of the joint out with a solvent, then sit down at a TV show for a half hour while working it up and back the whole time. After that, wash the metal dust you've just made out, and THEN lubricate it. The difference will be amazing.
