Most of my backglasss are sprayed with TT, and i've had no problems at all (touching wood as i write this..lol) Scary thought though after reading this thread, it made me go and check all my glasses for deterioration.. all good so far.
I have glasses that were done about six or seven yrs ago with TT, and some that i did with ordinary auto acrylic clear, even those one still look as good as the day i sealed them.
