    It must be the same stuff they use to coat eyeglasses to keep them from scratching.. Looking at my reading glasses, it only works for a while
    Epilog 24TT(somewhere between 35-45 watts), CorelX4, Photograv(the old one, it works!), HotStamping, Pantograph, Vulcanizer, PolymerPlatemaker, Sandblasting Cabinet, and a 30 year collection of Assorted 'Junque'

    Every time you make a typo, the errorists win

    I Have to think outside the box.. I don't fit in it anymore

    Experience is a wonderful thing.
    It enables you to recognize a mistake when you make it again.

    Every silver lining has a cloud around it

    Have you tried putting a wet rag on the paper and pressing the rag with hot clothing iron? Steam may release it. Getting the adhesive residue may require the use of an ammonia based cleaner but I have used WD40 for the residue of labels before. I don't know how WD40 will react to plexiglass.

    I've tried everything and baby oil and window cleaner to remove it worked for me. It takes some time, so let it soak in.

    If these are larger flexible pieces, how about bowing them and holding them in a clamp for a day or two. Perhaps that will help break the bond.

    I'd try protective coating on the concave side first.

    by mistake

    I had some pre cut acrylic to put over photos and the paper was taking forever to get as per usual, I put off the job because it was bothering me. We have had several 80 degree days and I sat down tonight figuring I had a long night ahead of me peeling paper...lo and behold both sides peeled off in one pull. So my thoughts on getting the paper to come off easliy is procrastinate until you absolutely have to do it and hope for some real hot weather.....

    Hi John, you might want to try this product, it's called Maskoff. I have used in the past with good success. I got mine at a local plastics distributor in the area. With a quick google search I found this site.

    Be sure to let it soak into the paper for 10-15 minutes.

  7. how to remove paper from plexi glass that has aged

    I spent a lot of time trying to remove protective paper and tried WD40 , goof off ,GOO gone mineral spirits and razor blade all to no avail or very little progress so I set it aside for a future project . Then i sold a food trailer that had stickers all over it and I asked the guy how did he remove them so quickly and he said he took it to a car wash and used the hot wax setting and they came right off . So I fired up my cheap pressure washer from HF and tried it out and it took it right off!! So give that a try .

    That was a good hint as I have a lot of old plexi with the paper stuck on
