I had such good luck I keep it in a pump oil can all the time, & add a little acetone if it's been sitting a long time between uses.

Did you use the old petro based ATF? That's what I used. I never saw anything about which blend to use, so I used what I had on hand. I save the synthetic ATF for my RV-4 brake lines. :-)

Actually, I can't speak to the chemistry of mixing the two, but if you put an equal quantity of each in a pumper oil can, shake it up, and squirt it on solidly rusted bolts/nuts & let it sit for a while, they *will* magically loosen with much less force than you would expect.

I used the technique on a Massey Ferguson tractor that hadn't been apart since the early '60s, & was amazed at how well it worked.

But no reason to take my word for it; for less than $10 (or maybe nothing, depending on how well your shop is equipped), you can check the 'science' for yourself. :-)
