gorilla tape would get you home just fine but do you really want to have a puncture on a downhill that lands you in the hospital for a week? IMHO it would be the height of foolishness to try to save a few bucks in this case. If you ride leisurely on the sidewalk at 6mph and getting a flat is no big thing, then ...suuuurrre... but I'd throw that tire out. I distinguish between a point puncture and a cut. A single thorn puncture is so small that I don't consider it to be something that makes the tire less safe, but any cut more than about 1/8 inch that compromises the underlying layers of tire is enough for me to throw that tire away. I'll bet there are some really strong boot materials that would be reasonable to use but I don't know that simple Gorilla tape is really that strong with regard to puncture resistance. Tear resistance...yeah...but that's very different from puncture resistance. Just an opinion....
