Ultraseal claim that their products are different from the competitors. No surprise there- but actually some of their differntiating "science" on their website at least sounds feasible. And claims to overcome the need to keep moving issue.
However, I remain sceptical about any magic liquid (or thixotropic gel) being able to fix most punctures before I even notice they have happened. I have accumulated about 10 punctures in my time on the roads. Of those only 1 has been "repairable" by normal garages. A couple of them have destroyed the tyre by the time I was able to stop safely - perhaps ultraseal would have prevented that becoming so serious? I have been carrying a can of the "magic get you home at 50 mph" aerosol stuff for the last 5 years (4 punctures in that time) and NONE of them could be fixed with it.
IMHO their is no substitute for a spare tyre. However having read the blurb on ultraseals website I am tempted to put it in all my tyres (including the trailer) - if it is cheap.
