The ATF-Acetone mix sounds interesting, I hadn't heard of it before, worth a try.
I believe that different stuff works for different kinds of rust or different kinds of "stuck".
There is no one "best" penetrating oil for all situations.
I prefer PB Blaster for most stuff, but will always try something else with the hopes that it works better.
Wonder if acetone and PB wold work any better than plain PB?
Does the acetone help the oil to wick into the rust/stuck parts?
