Jim:
You are correct, thank you..... and to David who I hope reads your
correction .....it is 50:50 acetone and Automatic Transmission Fluid
(ATF) and not Power Steering Fluid (PSF). For the purposes of what we
are talking about using this concoction, a 50:50 of either ATF or PWF
will probably work..... differences of the two include, as I
understand, heat tolerance and anti forming properties.....both are
petroleum products.
In addition to the boat experience, I used it once on a screw on my car
and an home plumbing application with success. Maybe both would have
come free without this concoction, but both came free with it, so it
gained my confidence. I keep 2 oz. bottle with an eye dropper
around..... if I could only remember where I put it.

idea how the power steering fluid compares to ATF, however...so I
can't make any calls that way.

Advice, that from my experience in these situations, I would agree
with. If the bolt won't turn, anything less than a perfect fit
will begin the 'stripping process' which will ultimately make the
job more difficult.
David, I have tried this 'home made penetration concoction' with
success......by volume, half and half of power steering fluid and
acetone......and make sure if you try this, it gets on the parts
you want unseized and not on other parts, like hoses, belts,
etc. I used an 'eye dropper' which I found very controllable
and exact.....almost no spillage. I loosen the seized bolts on my
mixing elbow and exhaust flange with this concoction before I got
into trouble with , maybe a broken bolt head.

I would NOT try to use an open end wrench of any kind to loosen a
bolt that is really stuck. There is too high a probability that
you will just round off the head and make your task even more
difficult. Use some kind of closed wrench, either the box end of
a combination wrench, or a socket, preferably a six point. From
your description it sounds like a socket is out of the question,
which is too bad. I would not try to use any kind of one size
fits all or adjustable for breaking it loose either. I have never
yet seen one that will reliably transmit torque as good as a
solid lump of metal.
Once the bolt is broke free there are many options. I like the
box end wrenches that have the ratchet built in, in
situations when a socket wrench cannot be used. They are almost
as good as combination wrenches for tight fitting situations and
the ratchet makes them a lot more convenient to use.

I was at the boat yesterday and tried to take the heat
exchanger off the engine (Universal M4-30) so I could
refurbish the seals and make sure it is clean
(http://www.pbase.com/mainecruising/heat_exchanger). One
bolt came off easily but the one on the starboard side is a
challenge. I cannot get a socket on it because something
from the engine or transmission is partially blocking frontal
access. I found my wrench selection on board is less than
adequate and I need to upgrade. I tried with a short 1/2"
open end wrench and was able to get it on, but could not
budge the bolt. I left it sprayed with penetrant hoping that
will loosen it.
I looked at other wrench types to see what would be useful
in this situation and came upon this ratcheting wrench I had
not seen before:

It looks like something useful to have on the boat as the
clamping action should work on both metric and SAE, it is
stainless and it ratchets. Has anyone tried something like
this?
The other type I am considering is the flex head ratcheting
wrenches:
