CowRC Udder Butter 8oz – Super Waterproof RC Grease


Udder Butter isn’t hardware-store grease in a fancy jar. It’s purpose-built for radio-controlled vehicles that get wet, dirty, and abused.


If you run crawlers, bashers, boats, or anything that sees mud or water — this is the stuff that keeps your drivetrain alive.


What makes Udder Butter different:


• Truly waterproof — won’t wash out in rain, mud, or puddles

• Thick, tacky formula that stays where you put it

• Great for gears, bearings, axles, diffs, pivots, and O-rings

• Reduces wear and noise in drivetrains

• Excellent corrosion protection for wet environments


This is the same grease trusted by hardcore RC builders and racers who don’t want surprise failures mid-run.
