Makes sense.  What about the stuff they use to "repair" cracked car
windscreens?  It's got much the same refractive index as glass (you can
*just* see distinctive "flower shapes" if you look, around a repaired
chip), and is flexible enough to move with the glass but strong enough
to stick the glass and plastic sheet together.
