3m Scotch Permanent Mounting Tape 1x50

A few years ago I mounted all of my prints on my walls with Scotch double-sided tape, and they are still all there! Recently I bought some new prints that needed mounting and thought I'd try "Gorilla" double-sided tape as I'd heard good things about it, but it was extremely hard to use as the backing was almost impossible to peel off. And withing a few hours all the prints that I'd used Gorilla tape on had fallen down! Maybe the surface was the issue - it's slightly rough dry wall with a coating of paint. So I bought a new roll of Scotch double-sided tape and stuck the prints to the wall with that with no problems at all, and the backing peels off without any problem.
