    Question To wd-40 or not to wd-40? That is my question.

    Any insights. Ive heard it both ways, whats the truth? For motors? Bearings?

    It really does help with rust protection, but it will get messy if you get it on the chassis and plastic parts. This is from bashing in dandelions with WD-40 on my axle carriers (accidentally got on there):



    If you get the new WD-40 can with the Smart Straw, it's really easy to spray those small bearings and parts that need to be sprayed down. It will smell for a little while, but the smell will go away.

    I love the stuff!! It works really well!!

    The only thing on my merv id wd-40 is maybe bolt/screw heads to help prevent rusting but i would not use it on bearings or anything like that to reduce friction that a proper oil/grease is intended. Ive heard a light wd-40 mist over the rc chassis is a good idea after cleaning to help easy dirt removal.

    This is true, people use it all the time on the inner fenders of off road rigs to help the mud wash off..

    So not on the motor? How about electronics cleaner?

    I've used electronics cleaner on my motors, no problem.

    Probably just a light mist will attract less dirt on the electronics and such, though.

    If you run in the wet... You must use WD-40 to prevent the steel parts from rusting. Go ahead, use it!
    What have you learned today?

    I've only used WD40 to blast out the bearings. I soaked metal bits in this stuff and have had success... no rusting since, and grit doesn't stick. It's been very good for the pillow balls:

    ive sprayed wd40 on my merv and rally, after i washed it and air dryed it. When im done with my jetski, cuz i ride in saltwater, i normally spray CRC 656..and i know that stuff is ok with plastic parts, so i might try spraying that on my rc cars after i wash them. Plus its a lubricant and its good stuff.
