Not good enough...
- Jan Erik, 13 April, 2026
The good news is that it sealed a puncture on the way home enough to get home. The bad news is that when I removed a sharp stone from the tyre at home and the tyre started leaking again, there was no way I could get it to seal again. Wheel turned so that the leak was at the bottom, tyre set to a very low pressure, it kept sputtering.
Pros & Cons
Clearly visible that your tyre has been punctured
Don't seal a small hole.

better occasionally pay more expensively for an "A" brand

To my regret, I thought I had made a bargain. Unfortunately, it had failed to seal the small hole in my tyre. So in the end there was sealant everywhere on the down tube of my frame, mixed with the dust.... And I could scrape and scrub it off afterwards.
