The other strategy is to use a grease gun to force grease into the
cylinder. A grease gun can actually generate considerable
pressure. Also, if you are successful, the piston does not fire
across the garage, which can happen with air pressure. Of course, if
the cylinder is that frozen, what are the chances that the cylinder
walls will be good enough to rebuild? Then you have to find another
core, or have it sleeved in brass or stainless. That probably isn't
really worth doing for a part that is available from the usual
suspects. Good luck.
