Default Convertible rear window becoming unglued...

After 9 years, the lower right corner of the rear convertible top window is becoming unglued. This seems to be localized to that corner area only, and the top is otherwise in perfect conditions. I do not want to replace the whole top right now, and I would rather attempt a repair.

I have searched the forums and found three postings on the subject. One recommends the following two adhesives:
3M 1300L
Bostik 2402

Anyone has a suggestion or can recommend an appropriate adhesive?

TIA

Default Fix it fast!

Mine also had a small area coming unglued. It rained one day while I was parked at my office. When I came out, the entire bottom edge and one entire side had separated. Had to buy a new top. Took two weeks to get the new top made and installed. Couldn't drive the TT. It sat in the driveway under a tarp. Fix it fast.

I'm having the same problem with my 2002 TT. The window started falling out today. Is there a repair that works?

Default Update....

I have tried the 3M glue. The problems are:
1. The glue is a light brown-yellow. Every single smudge is very visible on the black top. It really doesn't look good.
2. Application is a nightmare. I could not get it up properly.
3. This glue does become loose pretty fast. Count on re-applying every month or so.

It is not a viable solution in the long run. Top replacement seems the only permanent fix. :-((

Default Goop

After having the same problem with mine and doing research on the net I decided to go with "goop" as it is advertised that it works on fabric and glass. First I reglued the fabric strip back onto the window and held it in place to dry with clothes pins. Then I glued the fabric to fabric and glass with another application of goop.
First I released the top to reduce the tension on the window. I then applied the goop and held it in place with with a thick clear tape(not duct tape as it will leave a residue) I applied the glue on the outside first and it let it dry for 24hrs. then I re-applied the goop on the iside of the rear window. I was able to stuff furniture pillows in the back to keep pressure on the seams.
So far it's holding up although I haven't tried putting the top down yet. I live in Fla. and it's been extreemely hot and that hasn't had any effect on the glue job! The glue dries clear and I was able to use a razor blade on the outside of the window to clean up the over flow. The job looks almost 100% perfect.

mine completely came off lol... i pulled the whole top off the car and glued it back together using uv5200. You can find it at any marine supply store and some hardware. it's less than 20 bucks for a caulking gun size tube and works wonderful. its water proof and glues pretty much anything to anything. its held up great so far. 2 months and counting and i put the top down almost everyday. i live in south east nc it rains every other day and the its 95 degrees everyday. only draw back i found was set time is 24 hours and cure time is 7 days. also it comes in black sorry the rant.

I tried a couple of Home Depot Super Glue brands which worked great for about 6 or 8 months each, then failed again. After the second time my glass fell out, I took the roof to a custom upholsterer for a plastic, sewn-in replacement -- my idea -- that looks OK. Not good, just OK, but it does a great job of keeping the rain out.

Appearance (and future clouding) is not a big deal, since I almost always drive with the top down. Seat heaters and an 85-degree blower into the footwells can compensate for most of Atlanta's chilly days.

By the way, the guy had some wild convertible top replacement fabrics: animal prints, metallic flake, and some electric solid colors. Maybe next time, I'll get the zebra print ...

Did the same exact thing! Window is perfect no leaks. Took it an extra step and on the outside put a nice bead of black silicone. Ran my finger through it to get a nice flush look and then took razor and cleaned it up. U can do it fast and sloppy or take ur time and make it look professional. It's all up to you.

Default 2002 TT Roadster Convertible Window repair

After reading many posts on this subject of folks using Gorilla Glue, Rhino Glue, JB Weld and other adhesives, I decided to use 3M 08609. After the 24 hour indoor cure it seems very secure and looks professional. If it does not last at least a few years I will be surprised.

Tips:
Use gloves
Use a razor blade to remove the old adhesive from the window
Cut some dowels or other scrap wood to hold up the window from the inside, not too much pressure.
Use Acetone on window and top prior to applying 3M 08609
Others recommend using 3M adhesive primer before 08609 application, I chose not to
Check the inside of top near the window for any canvas coming loose and apply adhesive during the outside repair
Take the opportunity to apply Raggtopp protectant to the entire top after repair
