Don
I apologize for some misinformation on "liuid breathing".
http://en.wikipedia.org/wiki/Liquid_breathing
I got silicone oil mixed up with fluorocarbon oil in a senior moment. Fluorolube would probably make a good rubber lube, but probably too expensive. The fluorocarbons are better at dissolving oxygen. Except for mice, their use in diving seems to be mostly science fiction.
Sorry
Joe
