Better bushing lube; grease, oil, silicone/teflon spray?

[SteveK]

I have a little Duratrax Cliff Climber, and it's got bronze or some other type of metal bushings in it. Which do you guys think would make a better lube, grease, typical bushing oil for motors, or a thin teflon/silicone spray like Cow R/C Moo-Slick?

Actually DuPont makes two types of spray; a thin one similar to Moo-Slick (first one: http://www2.dupont.com/Consumer_Lubricants/en_US/products/silicone.html ) and a thicker stuff that is almost like a foam/grease (first one: http://www2.dupont.com/Consumer_Lubricants/en_US/products/dryfilm.html ). The one in the orange can works wonders on bearings.

Except for a BoLink Legends car that required it, I don't think I've ever actually run a car or truck with bushings. I may eventually put bushings in there, but for crawling around the yard and basement I just can't see bothering right now.

Good question, SteveK. I'd also actually be interested to know what all the "runner gurus" use to lube their diffs, joints, bearings, shafts & ball ends.

I'm installing a fresh set of rubber-sealed bearings in my Project CYANide Optima, and followed someone's suggestion to gently lift the rubber seal off and lubed the balls with Dura Lube. I've had this stuff forever, it seems; ever since it was one of those info-mercial miracle oils, it seems to be decent enough oil...and it's not getting used otherwise, so might as well use it. It's gotta be better than 3-in-1 oil, at least.
