@Pionir @pete @wav3ydave @adamrice @MrAndrewD @bicycling They, apparently, got a huge can of sealant meant for cars and shot that into the valve.Likely a liter+ in total. The butyl tube had a 6cm tear so the tire was basically completely filled with sealant.It didn’t work.

@Pionir @pete @wav3ydave @adamrice @MrAndrewD @bicycling Since we’re veering into discussing puncture sealant for butyl tubes, I’ll share this anecdote:I used to work in bike shops. Someone brought in a bike with a fast-leak puncture they tried to fix with butyl sealant.They figured if a little sealant would help with a slow-leak, a lot of sealant would help with a fast-leak.

@wav3ydave @pete @adamrice @MrAndrewD @bicycling I scrolled through all the replies and didn't see it mentioned yet, but I may have missed it:Rene Herse now sells TPU specific sealant: renehersecycles.com/shop/equip
