for your rusty bolt issues, I copied and pasted from another forum:
Machinist’s Workshop Mag™ recently published some information on various penetrating oils that I found
very interesting. 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 oil .......... Average load*
None ........................... 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 almost as good as “Kroil” for about 20% of the price.
Steve from Godwin-Singer says that ATF-Acetone mix is the best and you can also use ATF- lacquer
thinner 50 - 50 mix.
*ATF=Automatic Transmission Fluid
