The folks on the Old Tool Forums swear by this concoction, but it
smells worse than PB Blaster or equiv. and would likely evaporate
very quickly in open air.  Also, it's hard to rig a miniature red
straw to a WalMart bottle when you need pin point accuracy and some
aerosol pressure, but I have used it and have had success with it.  I
wonder how you would test such products against frozen rusted
parts.  I would think it would be impossible to duplicate each
rust-frozen application making the tests invalid.  Spraying WD-40 on
an item and having it subsequently not loosen something, only to
spray PB Blaster over the same area 30 minutes later, and it failed
too followed by the Acetone/ATF combo another 30 minutes later and
all of a sudden it works.   Was it the ATF/Acetone that did it, or
did the PB Blaster work after a 30 minute wait,  or did the WD-40
finally penetrate the rust after sitting for an hour or
better?  Inquiring minds wanna know........
