Acetone & pwr steering fluid mix to remove rust

[bigeasy1]

I have tried several rust penetrants to free up the seized 150 hp Johnson on my newly aquirred 20' Seafari with no luck.
I tried WD40,liquid wrench,PB Blaster,Free all,and (as recommended),Kroil,and a few home made concoctions.None of them worked yet.

So In my web search,I came across this on a few gear head sites.The guys on a few of these sites have claimed that a 50/50 mixture of Acetone and Power steering fluid worked better than any of the commercially made products,so I think I'm going to give it a try and see what happens.
I came across this on Bobs the oil guy site and thought you may find it interesting.I cut and pasted it below.Anyone ever try this?and if so what were your results?

PS.. I only copied the first page,you can find the original on bobs the oil guy site.

It looks like the original article was in the April/May 2007 issue of
Machinists Workshop.

Quote:
Machinist's Workshop magazine actually tested penetrants for break out
torque on rusted nuts. Significant results! They are below, as forwarded
by an ex-student and professional machinist, Bud Baker.
Don't forget the April 2007 "Machinist's Workshop" magazine comparison
test.

*They arranged a subjective test of all the popular penetrants 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

*The ATF-Acetone mix was a "home brew" mix of 50 - 50 automatic
transmission
fluid and acetone.*
*Note the "home brew" was better than any commercial product in this one
particular test. Our local machinist group mixed up a batch and we all now
use it with equally good results. Note also that "Liquid Wrench" is about
as good as "Kroil" for about 20% of the price.
The results have been widely quoted on the internet, but the picture in
the magazine allegedly shows power steering fluid and not ATF, and
according to lbender (who claims to be the author) in this thread, it
actually was power steering fluid (mixed with acetone) that they tested
with. Lbender begins participating in the thread on its second page.
