The back window on my convertible got a hole put in it last winter, since then I've just been using tape to keep it together. I have a new plastic window complete with trim that will make a suitable replacement, I just need to know what kind of adhesive and how to apply it so that it stays put when the top is up and folds accordingly when the top goes down. I'd like to remove the old back window as well.
Any auto parts store should have a strong silicone to hold it in
Either have it sewn in or get rid of the car. It will look like crap if you attempt to glue it in place.
Does it look to be sewn in?
