>From my buddy’s trawler list. . . . Hopefully it is as good on SS/Aluminum!
FYI… Machinist's Workshop MagT recently published some information on various penetrating oils that I found very interesting. 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 oils .......... Average torque load to loosen* No Oil used ................. 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 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. Our local machinist group mixed up a batch and we all now use it with equally good results. 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 best, but you can also use ATF and lacquer thinner in a 50-50 mix. *ATF=Automatic Transmission Fluid This actually works well, power-steering fluid also works as well as trans fluid!
