Sunroof Glass Edge Rubber Rippling/Tearing

I've had the same problem since the first winter in 2009/10, plus a little bit of cracking at the joint of the compound and the glass. It hasn't really gotten worse. I try to keep the snow broom and car wash pressure wand away from the edges.
What the heck were you doing washing the car anyway? It only got up to 20F (-7C) here.
20120731 update - I noticed that it was getting worse after the winter was over (sorry, no pics, camera's on the fritz). I brought it in to Acton Toyota Littleton MA Serving Boston | Used Toyota For Sale Massachusetts and they replaced the sunroof and wind deflector with no hassle whatsoever (and it only took two days for the parts to arrive). Job was done in two hours. They were very pleasant, do nice work, and provide free coffee, donuts, and breakfast sandwich while you wait.

 

I'm onlyguessing but it looks like some sort of solvent has affected the rubber?

 

Not a bad guess (solvents), but I think given the comments on other threads, as in this one, that it's a fairly common problem. I wish I knew what they call that surround material (probably a proprietary secret). I'm lucky, mine didn't get bad for almost 10 years...
