Loosening rusted bolts and nuts
In an email from my brother:
You guys may be interested in some interesting information that I found in the Studebaker Drivers Club rag. They gleaned it from another magazine, the Machinist's Workshop rag. It has to do with loosening of rusted bolts, and penetrants contribution to that effort. It was from an experiment repeated many times, them averaging the results for each penetrant. Every effort was made to ensure eveness in the rusting. Penetrant Average Torque None 516 lbs WD40 238 lbs PB Blaster 214 lbs Liquid Wrench 127 lbs Kano Kroil 106 lbs ATF-Acetone mix 53 lbs It would appear that WD40 and PB Blaster aren't nearly as effective as liquid wrench or Kano Kroil, but the home-brew mix of ATF and Acetone is a real winner.

Did they ever try pure acetone?

Did they test sea foam? That stuff is like liquid gold...costs a fortune!
Interesting on the Kano Kroil....I'll need to get some....or mix up some ATF and Acetone...  I think the kroil might be a better option....

The absolutely BEST way to loosen a rusted tight nut is to tighen it first, just enough to hear the corroded bond break, then loosen, you'll be amazed, works with phillips head screws too.

Hmmm, I wonder what the theory behind ATF-Acetone is? Acetone to eat into the corrosion and flush anything petroleum-based protecting it, and the ATF to lubricate the fresh metal? This is the second time I've read about the wonders of ATF.
