Default Regluing convertible glass window

'08 Audi A4 Looked in my rearview mirror this morning and saw some signs of water below the rear glass. Turns out to be a common problem with a few fixes on Youtube. The adhesives I saw people using were Rhino glue, Dap silicone and urethane windshield adhesive. Any thoughts on using clear 5200?

Its not glass but I think I came up with a clever idea for an older bmw rear window. should work

Its a 99 328 convertible that my daughter drives just in the spring and summer.
the plastic window thread and seams have dry rotted and window was unattached at corners and bottom

I used gorilla glue- follow instructions- you have to wet area slightly. then I used painters tape inside to hold magnets in place and then went outside and placed another magnet to hold the sections in place and tight. like every 3-6 inches. I did a small section each day for a couple days.

car is now weather tight again. I know at some point it will need a whole new top.

** the glue expands slightly and then had a dark yellow color that is noticeable after complete cure.

carefully used a razor knife and black marker. you cant tell at all now

note: car is just a kids summer ride, book value is only 2-3k so making it perfect isn't important. Just wanted weather tight and another year or two on top. Car sits under a car cover during the winters

Go to Midas, Speedy or any other reputable automotive glass installer and "buy" a tube of the proper sealant! Over the years I've easily have done a few dozen and have "never" had a leak.

3M makes a product specifically for this and a primer so it will bond. Like you said this is a very common problem and eventually the entire perimeter will fail. A good convertible top installer will have experience with this and can fix it but IMO long term you're better off replacing the top.
