Like CHG-ON, I too bought (and have used) the Safety Seal kit offered on Amazon for $45. It is a HIGH QUALITY kit. The tools will last a lifetime--all made in the USA. I used the kit without issue in one of my MS tires and have put about 5,000 miles on since the puncture without any problems--no leaking at all. On Amazon, search "safety seal tire repair kit" and it's the first product listed in the search result. I highly recommend the kit. A buddy of mine says many shops use this exact kit to perform their repairs.
