That`s what I used in my polishers. Just make sure it a high temperatures resistant grease and prefered to be based on lithium. The quality between the grease in my 2 polishers and the CRC High Temp Grease was very high. You feeled the difference between. The first polisher it where burned grease and also worned gear residue in the grease. And this not from many corrections with the 21mm longthrow polisher. The grease in the 3" mini polisher where looking okay but when I took it out you feeled it where watery feeling from the grease. So much less of a quality from both grease in the polishers. Didn`t think it where that kind of difference between them and the CRC High Temp Grease. And man what a difference from the noice levels from them after the grease was replaced. That sharp noice where you almost hear it`s wear on the gears is gone. So I`m very satisfied with the results I got by doing this. Shine Mate EX603 mini polisher which is like the Adam`s Swirl Killer Mini polisher is what I got. And was also pleasantly surprised at the high quality CNC parts in it. Even the oem grease looked good in it. It where a big difference with the CRC High Temp Grease and the sound from the polisher after the change. Just make sure so you don`t overfill with the grease you replace with and you are good to go.
