The thing is Ultra Seal is not a get you home substance if you get a puncture while running this in your tyres if it works properly you don't even know you have a puncture.
The way the salesmen show it at the trade stands is they spin a wheel on an axle and then ask people to press a bradle through the tyre which is your puncture. When the bradle is pulled out the air pressure in the tyre will push out into the hole the pink slime which seals the hole/puncture.
If a screw or nail stays in the tyre the slime will fill up any air escape.
In a tubed tyre this could work but normally the screw or nail will tear the innertube which the Ultra Seal can't seal because the hole/tear is normally too large.
When used with tubeless (IMHO) this is the most efficient. Ultraseal Kent - ultraseal, ultraseal puncture repair, puncture repair, repair a car tyre, repair a motorbike repair
