ANY HELP SOUGHT !!!!
I have a hairline fracture in my windshield.  It is small, but growing. 
Someone told me that they heard of putting some kind of glue a the growth
end.  I don't kow what kind of glue to use !!

I assume it should be (1) rigid like glass, (2) adherent to glass, and (3) 
similar to glass in terms of change due to temperature variations.

Any and all ideas appreciated.  Is glue the right idea ?

Check w/ your insurance co--some of them pay the full cost (no
deductable) to have it repaired, to prevent you from waiting until
it spreads and then have the insurance co pay to have it replaced.
Of course, this assumes you have comprehensive coverage.

Yes and no.  You must first drill a hole at the ends of the crack to
relieve the stress and stop it from spreading.  A Dremel tool, or other
high-speed drill with a fine bit will work.

The material used by the commercial operations is probably not an
unobtainium.  Its primary purpose is to remove the crazed appearance of
cracks, etc. so visibilty is improved.  It is a polycarbonate.
