Just installed a tubeless tire and had Orange sealant spray all over me during inflation. Strangely I didn’t have any issues with the presta valve. I think there might be other parts of mountain biking that suck more.

Fair enough. It’s just not for me I guess.

Meanwhile in America:

I like Rubio monocoat. It’s a two part catalyzed finish but is applied like a rub on poly. I used it for a walnut bathroom counter and it has held up well. https://www.rubiomonocoatusa.com/?country=us&reset
