I found an interesting post at the GS (http://www.thegsresources.com/_forum/showthread.php?t=159764) forum, figured people should know about it:
Penetrating Oils Compared
Machinist's Workshop magazine actually tested penetrants for break
out torque on rusted nuts. 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.
Penetrating oil ..... Average load
None ..................... 516 pounds
WD-40 .................. 238 pounds
PB Blaster ..............214 pounds
Liquid Wrench ...... 127 pounds
Kano Kroil ............ 106 pounds
ATF-Acetone mix... 53 pounds
ATF is found in any auto section and acetone is cheap at tractor supply
Wow! So all we need to do is come up with a catchy name and bottle an ATF-Acetone mix and we should be millionaires! Who's up for it? I'm too busy...
Since I have both ATF and acetone, I was interested in the mix. I followed some links and found this in one of copies of the same results test.

April 2007 "Machinist's Workshop" magazine comparison
...
*The ATF-Acetone mix was a "home brew" mix of 50% acetone - 50% automatic transmission fluid.*
*Note the "home brew" was better than any commercial product in this one
particular test. Our local machinist group mixed up a batch and we all now
use it with equally good results. Note also that "Liquid Wrench" is about
as good as "Kroil" for about 20% of the price. *
In truth it doesn't matter what you use on the bolt. Odds are you're going to round the head off anyhow.
Or maybe that's just me. :dash2: :dash2: :dash2: :dash2: :dash2:
Andy- it was left hand thread. Not your fault.
In true oil thread fashion- acetone is acetone, but which ATF? I'm pullin' for type F, since my Fords are well, old.
