If it was easy, then it would'nt be such a good adhesive, now would it?
Seriously, though, It peels off without any damage, but may take a bit more than just rolling it off like you can with barge. At least thats been my experience so far.
Another "solution" to the barge cement that lifts at the corners, etc. is to pack (which I do anymore, anyway, for first aid) a small tube of super glue. The little bit you use to stick down a lifting corner can be cleaned up later with acetone.....carefully, because it will damage a finish as well. Later, when it comes time to replace the leather strike or sideplate, you should be able to hide any areas that discolor or show from the use of the acetone. I still like the silicone idea though.
