I just tried such a vulcanizing tape, though not 3M brand, with mixed results. I.e. it is easy to get a very solid grip, but in practical situations you want to have leeway in regulating the tightness of the grip. For this vulcanizing tape, you pass too abruptly from a loose grip to very tight. Most often I want the accessory to hold tight, but still be able to change the angle if I want, while riding. Also in any kind of fall, I want the accessory to be able to shift rather than getting broken because it has to take on the full impact. This requires fine-tuning the grip, not that straightforward with the vulcanizing tape.
