I've used a ton of electrical tape over the years and its worked great in most cases, but in some applications its just hasn't worked out the way I wanted, for a few  examples: very small wires, sharp bends, protect small PC boards. With this stuff I just layer it on (most of the time I use a Q-tip) and wait a few minutes and the item is ready to go. Works great for me, try it you may love it too!
