Hi Tony, Well , you finally went for it - good for you. Once you finally get around to building it, you'll realize it's worth every penny. On the ceramic grease, the kit comes with 2 tubes. I believe that is more than enough. I built two of this already and for each tank I never used up more than one tube. By the way, this is one Tamiya tank you need to get right the first time. Going back to the hull and gearbox internals after final assembly is going to be an ordeal.
