Can be injected through the valve, seals holes of more than 6 mm and lasts up to 6 months. The perfect sealant for anyone looking for the ultimate in sealing power, durability and ease of use. The original formulation of the sealant, launched 2.5 years ago, was primarily designed to effectively seal punctures by maximising the surface area of the liquid latex for improved performance. Professional racers appreciated the practical application as they changed tyres frequently depending on race conditions and could simply add fresh sealant without having to inject it through the valve. The sealant dried out quickly when not in use and the composition of the longer carbon fibre strands made injection difficult and problematic, leading to a potentially messy installation if not handled carefully.
