For those who do their own restoration work, here's some interesting 
comparisons on penetrating oils.

Machinist's Workshop magazine actually tested penetrates for break-out 
torque on rusted nuts. 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 Oil and Average Load*


Nothing..................... 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 was a "home brew" mix of 50-50 automatic transmission 
fluid and acetone. Note the "home brew" was better than any commercial 
product in this one particular test.  Note also that "Liquid Wrench" is about as 
good as "Kroil" for about 20% of the price
