After you stick it to your shield, once you wear to the point that you would want to change your shield. All you have to do is peel one of the tear offs off exposing you a brand-new clear shield. After you pull the first one off you will now have three additional tear offs to pull off until you expose your original glass/shield. At this point I would stick a new tear off that has a set of four tear tear-off pulls, so you will never wear out your main shield. Works great for anything you would like to protect surface on. Such as window, mirror, windshield, countertop, touch screens on computers or CNC machines, etc.
Customers have used for so many different applications, on mirrors, CNC screen protectors, Jewelry stores glass countertops to stop scratching the glass of the show case, lower glass of a door that the family dog loves to scratch the crap out of it, and even front of fish tanks. Just to name a few.
