I just saw this thread, and it reminded me of a roll that I've had hanging around a long time. So I thought I would give it a try, after struggling with another roll a few years back. The roll was stuck solid, and after trying to roll it, to possibly loosen it up a little, and carefully trying to peel it, it still wouldn't budge. Then I thought maybe a little heat to loosen the adhesive. Sure enough after a few seconds, I think it was about 45 seconds before I could start peeling them (I did 15 seconds at a time). After carefully starting it and pulling them straight out and slow I had about a quarter of the roll separated in just a few minutes (with a couple of very quick reheats). You will want some type of backing paper to put them on as you go, I had some extra coil backing from a roll of the 1c bobcats. It does leave some adhesive residue on the face, I believe the warmer it was the more it left, but I could be wrong on that. I'm hoping Green Machines trick with the pure citrus will work to clean the faces, as I only had limited success with some soft soap and water that I had handy.
Below are the results.
