I have used the Safety Seal Tire Repair kit 3 times over the past year and have scored 3 for 3 in the perfect repair: department! Easy to use, professional results and the kit payed for itself after the second repair. I also like the fact that the tools are all metal, made very well and made in the USA!! I would highly recommend their kits and will not be without one (along with the great quality Viair portable air pump) in each of my vehicles. Yea I also have Road Side Assistance from GMC AND my Insurance Company but who wants to wait around for an hour or so when you can be back on the road in minutes. Sometimes the tire can even be repaired right on the vehicle taking no time at all. EXCELLENT PRODUCT Safety Seal!!
