Yes, the Stelvio shield has a protective hard coating film. Usually, this will come off when some strong adhesive material has been attached and removed.
If you have a new bike, it may be covered by warranty.
Anyone wanting a new shield, especially one with greater height or width, I highly recommend Gustafsson Plastic in St. Augustine FL. They have a base pattern obtained from our own Pyoung and they can produce a shield with all the bends and contours of the stock shield but with requested greater height and/or width.
