  1. Just found this little article about penetrating oils. Did you ever try the ATF - Aceton one?

    My cousin's dad, who pretty much gets credit in getting me interested in turning wrenches, used the ATF/Acetone mix for years and years. He always had some mixed up ready to use in one of those metal pump oil guns. That stuff works wonders. The main reason the aerosol canned penetrating oil gets used more (at my house) is the fact that it can be sprayed at greater distances with better precision/accuracy...but it still doesn't penetrate as well as the atf and acetone concoction.

    Ive been using KROIL as it was easy to purchase on TWO large cans.
    Works very well as claimed too !!!!!!

    All I use is the acetone/ATF mix. I've had excellent results from it while the commercial brands have failed me.
    I needed to take apart the brake lines on my Camaro a couple of years ago. None of them had ever been apart in almost 45 years. I sprayed the connections with acetone/ATF and let them sit overnight. The next day, the fittings all came apart easily with a flare wrench with no damage to the nuts on the lines. It convinced me.

    What do you guys put the acetone/ ATF in to spray it?

    Will a standard plastic sprayer work?

    Tried KROIL to remove the smog line exhaust manifold fittings on my 73 Survivor.

    I got the "Nut" to turn, but twisted the line(s)

    I have Kroil also. I only use it when really needed. It works good...but man does it really stink the place up.

    I picked up a couple of rechargeable spray cans at Menards. Mix the ATF and acetone in the can and put in some compressed air from your air compressor and you have the perfect spray can for the mix.
