I had a problem removing some old studs that were frozen in place on my '74B
block. A friend at work told me to try spraying them with "Aeroduster", a
product used to clean electronic parts. It is _very_ cold when sprayed for
any length of time and forms frost almost immediately. I tried this. It took
a hole can, standard aerosol size, but the coldness shrank the studs just
enough to break them free. Before I used this, I couldn't budge them. As I
sprayed each one, one at a time, each one started to free up as I tried to
unscrew them with the above mentioned method (two nuts tightened on the stud).
I believe that the company who makes "Aeroduster" is Miller-Stephens.
