I never have had a fletching come off using super glue gel or similar adhesives designed for fletching .It is difficult to clean off the shafts , but that is the downside of using adhesive that holds up well without the fletchings stripping off . With the arrow wraps , I usually soak them in hot water to strip off the wraps and fletchings .
For stripping one fletching , I just use an arrow stripper . It messes up the wrap a little , but it keeps me from having to strip all 3 fletchings to replace just one .
