I found this info from Machinist's Workshop Magazine which shows the mix of
50/50 automatic transmission fluid and acetone is the best penetrating fluid to use.
It worked better than any commercial product they used on a "rusty bolt test". The torque readings really reveal a big difference. I know many Fordbarner's alreadyuse the 50/50 mix but, it was interesting to see test results.
