As the others have mentioned, the sticky edges are a bit of an issue. You can get around that somewhat, if you are willing to do some "chemical" clean-up, with some Acetone or lacquer thinner. This will reduce the stickiness to some degree.
The real issue that I have with it is that you pretty much have to trim both sides at the same time, if you use the razor method. The adhesive is a little "soft", so the banding will pull to toward the cutter, potentially moving it enough to uncover the other side. It does tighten up some with time, but is never really as hard as a hot adhesive, machine applied or iron-on.
