Pinion Gear Grease?
#2
Diff pinion gear, inside the gearbox, use basically whatever grease you got to lightly coat the gears. The pinion and spur gear get nothing. Associated "black" grease is what came with my kits, and is nothing special about it. I personally use motorcycle maintenance waterproof grease for all my clingy slippery stuff needs. Shock building, gear coating, bearings, diff filling... a tub of the stuff will last me forever. The only thing I don't use it on is ball diffs in my 1/10 scale rides.

I agree with RustyUs on that ... sort of .
Pinion to Spur Gears
Plastic to Plastic = Nothing
Metal to Plastic = Nothing
Metal to Metal = A very very light coating of anything slippery ( requires regular cleaning as it holds the dirt )
