After the puncture is sealed, that area of the tire is left with a zone of carbon fiber reinforced latex bridging the top and bottom of the hole, helping to reduce the likelihood of future punctures in that area when compared to other sealant additives such as cornmeal, glitter, or fiberglass.
This superior sealing ability and hole reinforcing ability of the carbon fiber also allows for a higher concentration of anti-freeze agents in the sealant which means more effective sealing at low temperatures (6mm holes seal at 18deg F/ -7deg C), as well as longer lasting sealant (7-9months depending on humidity).
We recommend adding replenisher every 90-120 days depending on temperature and humidity where you live (see chart) to rejuvenate the sealant. Replenisher can also be used to replenish sealant on very porous tires during initial install. Some casing tires are very porous and will experience weeping of sealant throughout the casing sidewalls. Testing shows that weeping sidewalls can reduce sealant volume by 30% during the install, while also accelerating the aging of the sealant. Adding 30-50% of sealant volume back with the replenisher can ensure optimum performance and maximum life.
CO2 can be used temporarily to seat the tire, but should then be released and replaced with the floor pump to preserve the life of the sealant.
