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.<?XML:NAMESPACE PREFIX = O />
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
<?XML:NAMESPACE PREFIX = ST1 />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.
