I follow the Cycling about blog and have found allot of good info on subjects I am interested in. Although I have no want or need for the use of tubeless tires Alee Denham has made an informative video about sealants.

Thanks for the link.
Here's the text version: https://www.cyclingabout.com/best-tu...iets-test-road

I use sealant in tubular tyres and it works just fine at 80 psi.
Currently using Orange Seal because of these tests from 2014.
I did notice that the blog tests don't include high pressure tests (Fiets.nl) for Orange Seal but give it 3.5/5 for "Road & Gravel Tire Puncture Sealing"

I will give Peaty’s a try in my road tires. I’m a Brit and was a big fan of him as a DH racer!

I currently use Muc-Off, which has worked well for me over the last 5 years and scored well in the gravel tire test, but wasn’t included in the road tire test.

I've used this for > 10 years:

Pint of liquid latex (called 'Mold Builder' in the US)
Quart of RV water line anti-freeze (NOT auto radiator stuff)
Up to a cup of water to thin, yer choice

Mix very well and store in sealed container. Works on Mtn and road tires.

I was going to say Peaty's uses glitter, which they do, but when I just now looked it up, it says it is a biodegradeable glitter. I have a little pouch I carry sometimes as a spare, since it fits Peaty's valves. I haven't actually used it (my tires have Orange Seal endurance).
