Looks like it's working. It's nice to see somebody do this and give detailed long-term reports instead of the usual, "Yeah, I've got a friend who's buddy's cousin's dad did it, etc. etc."
It's not for me, but you've given me proof enough that I now consider this technique a feasible option for rapid and effective flat repairs on the rear where it seems like 99%, if not all, puncture flats occur, at least with any kind of riding I tend to do.
If I rode as much as you do, I'd strongly consider doing it.
