I have several sheets of old Plexiglass from which I can't remove the
paper backing. The adhesive apparently is dried out. I tried a heat gun
but that didn't help soften it. The clear film on the front side comes
off fine. Anybody have any ideas? Thanks.
I tried alcohol and had no luck, it just evaporated away. However, later I
poured alcohol on a piece and still had no luck, except it seeped down between
a sheet below and the next morning the paper slid off. The glue is gooey and can
be cleaned with alcohol and looks like the day it was made. Time is all it took.
Chem-peel - Specifically designed for that purpose and works very well
without harming the plex. I got mine from a plastic supply house,
imagine you'd have to do the same as it was clearly not a consumer
product. Seem to recall it was made by something like "Ogden Labs" in
