I am sure if you absolutely can't get a tubeless tire to seal it would be like hell but all the "horror" stories I have heard are a bit dramatic IMO. The splatter you see is due to me running much higher pressures than I should be since at my weight I should be running 60-65 PSI but I was running 80 PSI. Number two, people always complain how sealant got everywhere and how they magically were soaked with sealant, yet if you are running road tubeless there there really shouldn't be more than 2oz in each tire thus how soaked can you get, since my clothing kit was completely clean. Lastly, all of these sealants are water soluble thus cleaning them is super easy unless you let it caked on and let them completely dry out for days on end. I literally sprayed down my bike and got 80% of the sealant off and then wiped down with a microfiber cloth and got the rest off. Frankly this was no dirtier than cleaning after a wet ride.
