Tubs

Today's top tip. If, when pumping up a tub, it goes bang and loses all its air while you're fettling it in the living room, do not be tempted to try using Pitstop while you and the punctured tub are still in the living room.

Its a general problem with latex sealant and not limited to "insertion time". An already sealed tyre can "loose its plug" on a very hot day and start to discharge. Most common times for this to happen is during inflation--- a not atypical "living room" activity.
