But if the sealant did seal why did you try to plug it?
Dynaplug or a stan's dart are there for the life of the tire and you just need to top up the sealant to be ready for the next one...
No need to take the tire off until it's worn out or damaged beyond a plug.
I had a really big puncture that seeped if I added too much air. I rode with ~50psi for about an hour and it sealed up just fine after the sealant hardened a bit. Still good today!
