I've used a-lot of different grease on different cars, but for me this is an ESSENTIAL for any RC car. This along with a tube of Tamiya Cera-Grease HG is all you need to keep you car in perfect running condition for grease. I love this stuff!!
This is very high quality Tamiya grease - you sometimes get a tiny 1g pot of it wit Tamiya kits. This is 3g (3 times as much!) and is so much easier to use in the tube. The nozzle on the tube is very small and AW grease is very thick and sticky, so it's easy to just squeeze out a tiny amount onto a component. You can then move it around on the component with the nozzle of the tube too, because this stuff REALLY sticks!!
In the TRF 415 MSX instructions it shows putting this on things like universal driveshafts and stuff. I personally like using it in drift set-up diffs too it gives a really smooth, very long lasting tight differential if that's what you are looking for... works great for me for drifting! It is very sticky and thick, so care must be taken not to use too much!
This is much better value than buying the little pot, and as I said - it is much easier to apply from the tube rather than the small 1g tub. I know it seems like a small tube, but this stuff lasts ages as you don't need much, believe me!
