- Manufactured using 12 strands of high-tensile Kevlar fiber, the same materials used in bullet-proof vests
- Each BlackJack strand of fiber is individually impregnated with live butyl rubber. This compound is developed using carbon black, giving the repair its black color, making the repair almost invisible in the tire.
- BlackJack Repairs conform to size and shape of the injury, sealing out moisture and dirt, eliminating stress to the belts and preserving the tire integrity. This is the reason that BlackJack Tire Repairs are a PERMANENT repair.
