Hi Joseph,
I didn't use the little rubber mat, but I did apply the overlays on a
flat surface, on a video polishing dust cloth. In addition to the
curling, sometimes I noticed small "bubbles" in the overlays even
before they were applied.

Last summer, while trying to decide whether to discontinue their use on
DVD's, I applied overlays to some DVD's, and left them off another part
of the new arrivals. I have since gotten complaints on the ones that
had the overlays, but not a word on the ones that didn't. Coincidence?
I've stopped using them for DVD's. I still use them for CD's, and
haven't gotten any complaints on the CDs.
