Have to question the protocol of any test that ends up ranking muc-off way above Stans – that is not reality.
Any sealant that can do road tubeless at high pressure will be a big deal, though, so the silca one sounds interesting. Finish line had one with fibrous material a couple of years back and it was rubbish ime – it’s a challenging problem.
The performance v longevity of the sealant will be key. Something that works well on road but needs a refresh every week isn’t very appealing, but some compromise is likely necessary as you can’t expect too much from stuff that’s been in your tyres for 6 months.
