Machinist's Workshop magazine actually tested penetrants for break
away 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.

---------------------------------Average load
Penetrating oil ............ 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. A local machinist group mixed up a batch and 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.

Personally I have been using ATF for years as a general lubricant. It has rust prevention, it doesn't evaporate, it doesn't turn into varnish and its cheap.

I know politics, religion, and oil, can cause great debate. Matters of Faith often do.

My next topic: Vasaline [in the shop]

I've read this. I've also learned not to mix up too much ATF - Acetone unless its in a container that seals well or it'll evaporate on ya.

Personally I've had better luck in the past with PB than liquid wrench. Now I mostly use the Kroil. $$$$$$$$$$$$$ but good.

Thanks Al
