Hello Mark - I have long used the 50/50 acetone/ATF method for easing the removal of barrels from the receivers of the WWII rifles I often restore. It's easy to immerse the receiver/barrel joint in a tall jug like a cut-off Coke bottle for several days to let the low viscosity and surface tension of the acetone carry the ATF lubricant into the joint. However, I'm not so sure how to keep the very volatile acetone part of the mix around long enough to be really effective in a non-immersion situation, like most of our "corroded nut" applications, especially in a vertical or inverted position. While the plastic 2-liter Coke bottle worked fine for me with immersion times up to a month (adding acetone every couple of days to replenish that lost to evaporation), I'm sure that metal or glass would be even better for storage - you can keep it capped to minimize evaporation of the acetone. Obviously, the only time you can be sure you have a 50/50 ratio is when you first mix it up; the acetone evaporates pretty quickly if left open thereafter. On the other hand, I doubt that the exact 50/50 ratio is significant at all - you just need enough acetone to thin out the higher-viscosity ATF and carry it into the threads. Perhaps an even better method might combine acetone with the Gibbs product to get the probably superior Gibbs stuff even farther into the threads.

For example, can it be stored in an old spray bottle like a Windex pump bottle or must it be kept in something other than plastic, like a metal lacquer thinner can?

Some of you might appreciate his. The magazine reports they tested penetrates for break out torque on rusted uts. hey are below, as forwarded by an ex-student and professional machinist. They rranged a subjective test of all the popular penetrates with the control being he torque required to remove the nut from a "scientifically rusted" nvironment. Penetrating oils ........... Average torque load to loosen* o Oil used ...................516 pounds D-40 ..................... ... 238 pounds B Blaster .................... 214 pounds iquid Wrench ...............127 pounds ano Kroil .................... 106 pounds TF*-Acetone mix............53 pounds he ATF-Acetone mix is a "home brew" mix of 50 - 50 automatic transmission fluid nd acetone. Note this "home brew" released bolts better than any commercial roduct in this one particular test. ur local machinist group mixed up a batch and we all now use it with equally ood results. Note also that "Liquid Wrench" is almost as good as "Kroil" for bout 20% of the price. teve from Godwin-Singer says that ATF-Acetone mix is best, but you can also use TF and lacquer thinner in a 50-50 mix.
