Freud,
Just curious, did they say how long they let the solutions set on the parts before they did the test? I wonder how long the Acetone would stay suspended in the ATF before it evaporates.
Over the years I have taken about 50 Flathead Ford engines apart and the best I found for the job was the Kroil. And I found out about it by mistake while working at a Nuclear Power Plant. Wish I would have known about Acetone & ATF. Over the years I have never had much luck with Liquid Wrench, very surprised to see it rate so high.
