I’ve had a puncture and used the Stans dart to seal it while out on the trail, but it didn’t work. I even put two darts in but sealant is kind of spraying out around the hole and not sealing. I even put additional sealant in the tire too, to try to flood it to no avail. Like in Stan’s Instructional video I have the puncture at the bottom So that sealant kind of floods around the dart to activate it but still to no avail I don’t know. Should I wait a few minutes? That does not seem wise. I inserted the darts as quickly as I could. Is there any other kind of little tricks of the trade to get the dart to seal appropriately?
