The Hutchinson Fast Air is the only sealant Hutchinson recommends with their tubeless tires. It is a latex based sealant that comes in a 75ml CO2 canister. It both inflates tires from 0 psi and seals from punctures. It can be applied before initial inflation or on a ride after a tire has gone flat we recommend inspecting tire for cuts before using Fast Air. It can inflate a 26x2. 0 MTB tire to 30psi or a 700x23 road tire to 80psi in less than 90 seconds. In both cases, the pressure is a bit low, but should be enough to ride home on. We recommend being careful when applying. We've found that having the can off center results in sealant squirting out onto the rim and leaving a latex hairball.
