Part of my rear window seal (The one that actually goes around the window) is starting to come off. Any advise on what adhesive to use on it?

 

Thats just a gm problem. You see 2001 cars on the lot with that problem. You also see many cars with the whole peice removed. I wouldnt worry about it, but if you really want it fixed go to a glass shop and they will take care of it for you.
