Ok, a bit more serious answer, silicone is not so good, it has to low viscosity and will smear forever, so will teflon, neither is particurlary good on either tripod or bike (been a roadie for a few years, dry wax-like lube is the best for derailleur chains).

As for tripod, well you might want to have something with a high viscosity, making sure it will stay in its place and not keep smearing on hands and shoulder. Ordinary bearing grease applied with a syringe has worked for me. An even more slow flowing alternative on threads (not joints) is bees wax, sounds a bit ridiculous, but actually works good, keeps em running smooth.

On another note, horse grease is terrific for deep frying french fries.
