Brian,
As I said in my post I know what it where it came from and what it was originally used for so i am not "intrigued" by it. I am speaking from personal experience in using it for over 30 years and I have found it is an excellent penetrating solution for freeing rusted and corroded parts. The ingredients are what many people already have in their shops so mix up a couple of ounces and try it your self.

Pete, I didn't quote or refer to you personally, my post was more for the wider readership. That said, while I believe you that it works well as a penetrant owing to one or two ingredients in it, that doesn't mean
all the ingredients are required for the penetration function, and almost certainly several ingredients are being wasted. Consider that to
have "Ed's Red" one must brew it himself. I'm just pointing out the futility (and expense) of rounding up all four (or more, depending on which recipe one uses) ingredients, when in fact one (or more) are for bore cleaning and protection, not penetrating rusted joints. In particular, I question the acetone, in part because that's nasty smelly stuff I'd prefer to avoid if it's superfluous.

Brian,
The active ingredients are the ATV (detergent properties) and the acetone (strong solvent) but as you probably know acetone evaporates rapidly. I'm sure the kerosene is intended to restrict evaporation. I see mineral spirits recommended all over the place (maybe even in the Porsche manual?) for grease cutting. I personally had and have all of the ingredients in my shop and as I said I think many do as well. It's not like you have to run all over the place to find these and I wouldn't say "several ingredients are being wasted" as there are only 4 to begin with.

Here's what it says in a nutshell:
Machinist's Workshop magazine actually tested penetrates for break out torque on rusted nuts.
Significant results! They are below.
They arranged a subjective test of all the popular penetrates with the control being the torque required to remove the nut from a "scientifically rusted" environment.
Penetrating oil ..... Average load
None ...................... 516 pounds
WD-40 .................... 238 pounds
PB Blaster .............. 214 pounds
Liquid Wrench ........ 127 pounds
Kano Kroil ............... 106 pounds
ATF-Acetone mix.......53 pounds
