Default Evaluate my C5Z rear window seal

Car only has 25K miles, and while the rear window seal looks perfect, I noticed this when doing some cleaning. The seal is still in the channel between the glass and roof, the ends of the seal are still bonded tightly, but this part along the middle is loose.

What would you guys do? Leave it alone, or use some type of adhesive? I am a little OCD about this car, so I am ready to buy whatever adhesive I am supposed to use. Suggestions?

I think they have a C channel that goes onto the glass, all the way around, before the glass goes into the car. Therefore, the molding isn't actually attached to the car, just the glass, which is glued to the car. Mine can be lifted the same way. When I get around to a repaint I plan to eliminate the molding completely.

That makes sense, as I see no signs of adhesive anywhere. Just kind of bugs me that it is so loose. I never noticed it with my previous C5Z. Damned GM quality. LOL

My '04 does the same. Lays flat, but can easily be lifted as your pic shows.

Here is the window reveal molding. You can replace this with the window in the car still.

I plan to just have my window removed and replace it then.

At just 25K miles, I am hoping it doesn't need replacement. I was just curious about why a portion of it appeared to be loose.

It is loose because it is basically stretched/torn from itself.

Now mind you, it is not the actual window seal.. It is just a molding to cover the seal.

I need my actual seal redone as a good amount of high pressure water in the lower right corner will spritz some water past the seal into the car.

Mine is definitely not torn or separated, as it can't be pulled up from the body channel. It is definitely still intact and is seated under the lip of the glass. I was also under the impression that the reveal molding IS the seal. I always thought the molding was attached to the window, and then the window was installed using windshield adhesive. In the side-view picture below, you can see the groove the window sits in on the right. The left side of the molding shown is where mine is loose. Just where that sits on the body.

The molding is only for pretty, the seal is made by the urethane between the glass and the body. We actually have "rope" tape that we tuck under the lip of the molding where it meets the body. It's used to pull the lip up so that we can prep for and paint as far under it as possible. Over time the moldings shrink, lose flexibility, and crack. Yours sounds similar to mine, just a little looser fitting maybe. Mine gets water trapped under it that seeps out after a wash and seeps out seemingly forever. If you blow dry the car you'll see it lift up when you pass by it.

Yep, mine flips up when I use my blower. Bugs the hell out of me. Time for a little light adhesive...

That is what I thought. There is no separate "seal", just the urethane adhesive. Then this damned flappy-flap molding that is annoying me. LOL
