Hi All,
this from a mate in NZ. Thought it might be useful for someone.
Dont know if these products are available outside the Antipodes but it
might give you ideas.
Pat.
Machinist's Workshop MagT recently published some information on various
penetrating oils
Some of you might appreciate this. The magazine reports they tested
penetrates for break out torque on rusted nuts.
They are below, as forwarded by an ex-student and professional
machinist. They arranged a subjective test of all the popular penetrates
with the control being the torque required to remove the nut from a
"scientifically rusted" environment.
*Penetrating oils ........... Average torque load to loosen*
No Oil used ................... 516 pounds
WD-40 ..................... ... 238 pounds
PB Blaster .................... 214 pounds
Liquid Wrench ...............127 pounds
Kano Kroil .................... 106 pounds
ATF*-Acetone mix............53 pounds
The ATF-Acetone mix is a "home brew" mix of 50 - 50 automatic
transmission fluid and acetone. Note this "home brew" released bolts
better than any commercial product in this one particular test.

I read about this several years ago, & used the mix on a 1950's era
Massey Ferguson tractor when I had to disassemble to replace the head. I
can testify; it works.
