    As Al said, acetone is a solvent Cory, used here in boat building and repair but tons of other uses. In fiberglass work, it cleans and preps the surface to allow new coats of resin and glass to adhere to existing layers. It evaporates at an amazing rate. It works great clean fiberglass resin (and sap) off your skin but that's probably not too smart. It gets cold as it evaporates and will dry your skin out quick.

    Thread we had on this way back. http://chainsawrepair.createaforum.c...g-oils-tested/

    See if I can pull some details out.

    Machinist's Workshop magazine tested penetrants for break out torque on rusted nuts with significant results!

    They arranged a subjective test of all the popular penetrants with the
    control being the torque required to remove the nut from a
    "scientifically rusted" environment (obviously a BIG nut!).

    Penetrating oil ...... Average torque



    None ....................... 516 ft lbs



    WD-40 ................... 238 ft lbs



    PB Blaster .............. 214 ft lbs



    Liquid Wrench ..... 127 ft lbs



    Kano Kroil ............. 106 ft lbs



    ATF-Acetone mix....53 ft lbs



    The ATF-Acetone mix was a "home brew" mix of 50 - 50 automatic
    transmission fluid and acetone. Note the "home brew" was better than any
    commercial product in this one particular test. Our local machinistgroup mixed up a batch and we all now use it with equally good results.

    Is the ATF similar to hydrolic oil ? I never put my hands in it.

    I've noticed on a rusty bolt it will start bubbling at the hole, making it look like it's penetrating. I had some ZEP stuff used to do that.

    I tried ATF drain oil from changing my sisters Honda Accord for bar oil. Not much of a lubricant in that application. I was surprised.

    I think ATF varies a lot. Some of the new stuff smells like cat whiz.

    Just as general info DHMO is a super solvent used in industry .Technical grade did have amounts of mercury in it .Medical grade not recommended for humans was used on the joints of race horses and had no mercury .

    Veterinarins carried it .If you use it be very careful because it's skin absorptive

    Tight thread even, might need penetrating fluid to loosen it up
