That wasn't the point, Orval. The original discussion revolved around the
tendency of most aircraft tubes to diffuse air through the walls of the
tube -- deflate themselves by spontaneous diffusion as it were. THe reason
given was that the specification for aircraft tubes uses a material that is
obsolete in the real world but still used in the make-believe world of
aviation.

Somebody brought up the point that Desser (via Michelin?) has come up with a
"no leak" tube that is blessed for aviation use. Some of the group on here
reported that the "no leak" was in fact just that and a few of the folks
plan on switching to that tube at the next opportunity.

Why not patch the tube? I have done it several times and have not
detected any problems. Just be sure to use the "hot patch" method.
