Its fine brush tip delivers a controlled amount of oil — Tamiya recommends its Mini 4WD F Grease — directly to the point of contact rather than flooding the surrounding parts. The same applicator doubles as a cleaning tool, since flushing a part with oil helps lift out old grease and grit before it is wiped away. As a maintenance tool rather than a chassis part, Tamiya lists it as usable across its entire chassis range, from the older Type 3 through the current MS, AR, MA, VZ, and ME chassis, since gear and bearing maintenance is common to every generation of Mini 4WD machine. Released in November 2014 as Grade-Up Part No.465, it is sized to sit in a pit box alongside the F Grease bottle it is designed to dispense, refillable rather than disposable.
