What grease in the Hotshot gearboxes?

[will04]

I'm starting my hotshot build today and I was just wondering what grease you guys use in the front and rear Hotshot gearbox. I bought some Tamiya anti-wear grease and my question is, do you use the ceramic grease on the white plastic gears and the AW grease on the metal parts and gears in the gearbox, or do you use the AW grease on all the internals of the gear box to give it that limmited slip effect?
