I had a similar problem
About 2 years ago, I noticed the my back windows were separating and debonding from the canopy. Thank goodness I had the foresight to recognize that this can separate and I had the windows removed rebonded , fiberglassed and painted by a guy with lots of experience in fiberglass. I did not build my 10, so I wanted to get someone with experience. Sorry you had to go thru this scary experience, but I must say I?m proud of myself for recognizing this and being pro active about it.
