Lisle Tool markets a nice impact screwdriver. However, the penetrating oil test is very interesting. I always liked Liquid Wrench and the numbers are good for the product.

I tried PB Blaster on a sticky door hinge and the results were poor.

I recently heard about the Acetone/ATF mix and think I will try it given it can be mixed for an oil can. The friction modifiers in the ATF are probably at work.

I'll take a nut, bolt, and washers over to the tooling shop heat them cherry red and put them under the hood of my car for awhile. I'll torque the setup to 100 lbft. I have a torque wrench that goes to 600 lbft.

However, I never took old Packards apart without soaking them in penetrating oil and letting them sit.
