What usually happens is that people glue the tire onto the rim so tightly that it can only be removed destructively. So the desire is to glue the protector strip on so tightly that it will never come off again, no matter what. It's much better to glue the tire onto the rim in such a fashion that it can be removed in a non-destructive way. Lost art, perhaps?Why would you even mess with cyanoacrylates is beyond me.
Good tip, saw a Blanco wrench video the other day from the Giro, he used a screwdriver under the tire once he got it lifted to work his way around.A tip: When removing a tubular tire, start by peeling up the protector strip until you have enough of it off the rim to put the tips of your thumbs under it. That way you pull the protector strip and the tire off as one unit.
