I have some 1/16 cast acrylic I bought a 4' x 8' sheet of and apparently it's the cheap stuff (not acrylite). There are no markings on the paper at all and the paper is a real bear to get off (brown paper). It's stuck too well and the paper just tears into pieces. It can easily take 20 minutes to get the paper off a 12" x 24" piece of 1 side. Anyone got any tips or tricks on how to get this paper off easily?
