If you want a tough product, get some Shoe Goo from shoe section at Walmart. Clean and prep area. Apply in thin layer and let dry 4-6 hrs. This stuff is runny at first so have hole on top of tire. Apply coats after in 2-4 hr intervals. When all is dry you won't be able to get your nail to dent this stuff!!
