Driver's side mirror delaminating?

["Bertenyi, Tamas" <Tamas.Bertenyi@nrc.ca>]

Hi,
My '90 90q20v's driver's side rear view mirror seems to be 
"delaminating". It started near the edges and has over the last six 
months worked itself over half the glass. Has anyone else experienced 
this? Is there a fix that a mirror/glass-shop can do or do I need to 
replace the component? Note that the glass is anti-glare tinted and 
heated. Dealer wants $90CDN.

RELATED EVENT: So there I was at the dealer pricing out a new mirror 
glass. I park my little black car in the lot next to what I thought 
was just another black 911. Then I noticed the spoiler. Then I noticed 
the wheels. Then I noticed the yellow Porsche brake calipers peeking 
out from behind the wheels. Then I noticed three or four mechanics 
giving me dirty looks for parking next to the car. Then I say to 
myself: "Oh, I get it! This is 911Turbo S!" Holy crapolla! I don't 
know about the rest of the world, but Canada received exactly two of 
these limited, high-powered cars and I was staring at one of them. 
What can I say but "gorgeous". Priced at almost $250K CDN, it would 
seem a better deal than a house in the suburbs, n'est pas?
