    Default Convertible Rear Window - How to Refasten: Copied from CF

    http://forums.corvetteforum.com/show....php?t=1766844

    My 2001 convertible is my everyday car. I drive it in rain, snow and good weather. It is and always has been garaged. Three weeks ago at about 128,000 miles the back glass window separated from the top. The separation first started at the top and when it got to the sides and started separating at the bottom I stopped driving it.

    Iíve done lots of research on this site and others (including BMW, Audi and other convertible top postings). The results are that upholstery people usually say the sealing process is high pressure done under heat at the factory and there is no way to duplicate it in the field so you have to replace the top. Estimates for top replacement range from lows in the area of $500 to $1000 to a high of $3000 with the average being $1000 to $1500.

    Some people report glue attempts with total failures after days or weeks. Others report glue success and the glue holding after much longer times.

    Those reporting glue success used a variety of glues including: JB Weld, Black silicone RTV sealant, pure clear silicone sealer, 3M high black weatherstrip adhesive, and urethane windshield glue. One person posted that he used a cyanoacrylate glue that he got at a hobby shop. Super glue and its various other names are cyanoacrylate glues.

    I did my own research and settled on Rhino Glue which is a specially formulated cyanoacrylate that is waterproof, weatherproof and completely resistant to heat and cold. See www.rhinoglue.com for more information.



    I was not able to find this glue in any store and bought it online. This is a totally different glue than Liquid Nails Rhino Ultra Glue. Do not buy the Liquid Nails kind.

    Here are pictures of what the separation looked like before I started gluing.

    The first one was taken when the separation first started. Compare it with the ones below with the suction cups and you can see the progression of the separation down the side with just a little more driving.

    My advice is to catch it before the window comes completely loose.









    These round red things are suction dent pullers.






    I found these online. They come in a 1, 2, 3 or 4 suction cup variety. www.cvfsupplycompany.com/sucusucupdep3.html. I bought the 4 cup variety without thinking. I got 2 of them (only needed one in the end) for $30 and that included the shipping. When they arrived, I realized that they were too large for the window so I cut them in half. A better choice would have been either the 2 cup or 3 cup ones. I then rigged up a way to pull them so that the glass would be pulled against the fabric. You can see that this simply involved screwing an eye into the rafter above.



    I found that if I unlatched the top and lifted it about a foot that it relieved the stretched fabric enough to manually push it against the glass. Note the rubber mallet I used to hold the front of the top up.



    I then applied the glue around the glass about 3 to 6 inches at a time. Be careful and test this out before you apply the glue. I made the mistake of starting on the sides and moving toward the middle and was left with a significant bunching at the middle. The glue set up so fast that I actually had to cut the top away from the glass at the corner to smooth out the bunching. At the finish of the job, I was still left with a little bunching at the drivers side. As Iím not a perfectionist and it isnít very noticeable, I havenít tried to correct it.

    This is the finished job before I removed the dent pullers.



    I did the job at 7 PM and left the suction cups attached until the next morning at about 8 AM. I then drove the car to an automated carwash which I figured would be a great test for the bonding strength. It came through with flying colors - no separation of the window from the top and no sign of leaking.

    I then drove it 50 miles with no sign of any separation.

    If the glue is as advertised, judging by the part I had to remove and redo, I expect it will hold up for a very long time.

    Wish I'd seen this a year ago... would've saved me about $1600. Live and learn.

    Good post Shooter and considering our C4 and C5 convertibles are getting older everyday, probably a timely one too.

    Amen to that J.A.! I joined this site 2 weeks too late! Cost me $1200. The top company told me the window couldn't be repaired....BY THEM!!!

    I'm convinced. I think this thread is topical enough that we ought to make it "sticky" at the top of the forum, as a resource to other C5 'Vert owners.

    I agree Patrick... I bookmarked it in a special folder a couple of weeks ago so that I could easily access it for the next member that posts the Convertible Blues.

    Wow is that cool!!
    Great work six shooter, takes a lot of imagination to come up with that.

    The rear window in my '98 started to seperate this spring just as you described. I used the 3M marine sealant. Serious stuff! I spread a thin bead around the mating areas (once cleaned) and then pressed the window back into the place it belongs, without opening the top. I then used a couple of rolls of duct tape to wedge inbetween the tonneau cover and the rear window, all inside the car. It took aome manipulating to get them to set still, but then left for about a week. The 3M adhesive was thin enough to seal with the remaining factory seal to be watertight . It lasted for months of washing until it was replaced after a deer horn pierced it. The repair place charged $1500.

    Best of luck!!

    Default Great fix

    My brother's 2000 failed rear window was just recently replaced with a vinyl window sewn in at an upholstery shop for $300.00 which has been satisfactory -- but I think not as good your fix. For one thing, he lost the use of the heated defroster and the vinyl will certainly cloud-up at some time in the future. And, of course, it is not the original design. Still, it works for my brother and he is pleased with it. And, it will always be possible to return to the original. What is aggravating is the fact that the design of the convertable top could have prevented this type of common problem. A slight realignment of the supporting tubes could have obviated the extreme pressure which hastens the fabric separation.

    This will NOT work. I went through this exact procedure and it will hold for several months. Glue gets hard and releases window.

    I have designed a 2 piece clamp that will surround the window and hold.

    Still in prototype but once installed will fix.

    This will be a color matched 2 piece predrilled bracket . Holes will be drilled trough the soft part of top .

    Hollow top will go through and be screw from inside..and hold original glass.

    Watch for it. Try E-6000 for another fix...It is more resillient

    The method I used see link above on my last post to this thread. The fix lasted about one year the first time. I repeated the method after cleaning off the old RTV and it once again is holding. Tom

    I used two-part epoxy. Propped up the front, cleaned the glass, put a bead of epoxy around and then jammed two broom sticks inside from behind the seat to the glass to hold it in place a couple of bricks on the outside for opposing pressure. The next day it was cured and has endured over a year and 150 mph. I have faith in my fix and it was the most inexpensive. Epoxy is a strong adhesive.
