<VV> Rear Glass Explosion

[Brown, David]

OK, I have a weird one to see who else has had this happen.  Today, I
removed the rear trim around the rear window glass on my wife's 65 4-dr
sedan (checking for rust, pre- body & paint work).  No nicks or damage
to the glass occurred.  The good news is the metal is perfect.  However,
about 15 minutes later, while working on removing the trim from the
front glass, I heard a loud "pop" like a large garbage bag being blown
up.  After searching all around I suddenly realized that the rear glass
was still in place, but in a million tiny bits.  There is one spot near
the bottom edge where the breakage pattern looks as though it may have
started there, but there is no damage at that edge.  In fact that spot
is not even where I had been working (releasing of the clips from the
trim).  Any thoughts as to why this occurred?  Also, how do I remove it
& clean it up?  Should I apply a liberal amount of duct tape before
trying to remove?
