         It's *how* you glue the mirror in palce.  Use RTV gasket seal, ro
a similar silicon based type of cauking.  use very small dots - about 1/4
to 1/2" of an inch wide, and use several of them, well spaced apart -
depending of course on the size of your mirror.  For example, this stuff is
both strng and lexable enough , three "dots' can hold a full
thickness, 8" mirror comfortably.
