Karl,
Thanks for the feedback. I only wished your suggestions would do the
trick. Believe me, I've tried all of them- more than once! I don't
think
the problem is that the adhesive isn't sticking to either the glass or
the
mounting button. There's still plenty of adhesive residue on both
surfaces.
My guess is that this stuff just isn't strong enough. In fact, I got a
reply
from someone who has experienced the same problem on his Ford
Bronco, and I thing this might be a clue. Mirror assemblies on larger
vehicles (mine's an Astro Van) are often heavier than the ones on
passenger
cars. My experience has been that once glued the mirror does tend to
stay
in place as long as no one tries to readjust it. I think the last time I
reattached it was about 2 years ago. Usually I'm the only one who
drives it, but recently both my wife and son drove it and both readjusted
the mirror. When I tried moving it back, it came loose. Apparently
these
readjustments were the kiss of death for the adhesive.
Since I didn't start having this problem until after the windshield
replacement,
I have to assume that whatever GM used originally to attach the mirror
was
much stronger than the Permatex adhesive.
I suppose I could try my local Chevy dealer.
