This Tamiya (#87099) Ceramic Grease HG is very handy during maintenance a RC car kit. It is best use to replace the TAMIYA supplied grease from the kit. This ceramic grease is white in color. I have tested it in my RC car kit, it performs cooler and quieter, which prolong the lifespan of each individual moving parts. This grease is best applied on moving parts like gears and shafts even the plastics and metals together. This grease is a great investment and it lasts very long due to its ample quantity of the grease.
