A lot of people on this forum seem to recommend Lucas Red N Tacky grease for metal gears. I almost picked up a tube today but I popped off the cap and it really smells bad! (Like toxic lol). Do people only use it because it's cheaper than "RC" grease? Or it really actually better? I will be getting a Gelande 2 and want to re-grease the gears since apparently they are pretty dry stock. I have a bunch of RC grease tubes already that came with other kits (Losi, Tamiya, Axial) is there really any difference? Should I get the red N Tacky anyways? I want to protect my gears as well as possible since they're not exactly cheap..
