RE: [DML] Windshield Cracked.

["Tom Tait" <TTait@xxxxxxxxxx>]

Per Don at DMC in Garden Grove, the inner layer of glass is notably
thinner than other windshields.  That makes it obviously more fragile as
well. Problems come when either a glued mirror is removed, or when the
glass expands and contracts at a different thermal rate than the mirror
base.  The adhesive pads have a bit of flexibility and can allow for the
glass to expand and contract at a different rate than the mirror base.

It follows that when mirrors are glued and then fall off that it was
likely due to some force rather than deterioration of the glue per se.
It sounds like in these cases the glass proved tougher than the glue,
and fortunately the glue eventually sheared and worked loose.  With
better glue, the glass can start to crack.  Once it starts, it's all
over.  

It happened to my car before I got it.  All the vendors sell the right
double stick tape and it probably costs less than a tube of superglue.
My new windshield ran $700-800 installed and shipped.  The math is easy.
I'm sure there are a number of folks here that are braver than I am that
have had some luck with glue, but I'm too cheap to take the chance.

A final note, one need not make the same mistake twice.  My new
windshield from DMCH came with a new mirror mounting pad at no extra
charge!

Anybody know why our windshields crack if the mirror's
glued directly to them when so many other windshields
are fine?  Thinner/different glass?  The very flat
design?  (Do similar shaped ones like Lotus require
the tape-type installs?)

Just curious,
