The emergency film serves as a temporary replacement for destroyed side or rear windows and thus maintains the mobility of the vehicle.Window Guard™ is a self-adhesive, transparent PE film (film thickness: 83 µm = 0.083 mm) with high transparency. The perforation makes it particularly easy to apply. The adhesive film is so strong that the film can even be stretched tightly during application. This reduces wind noise to a minimum. If the film is applied without creases, the vehicle can easily withstand a heavy rain shower.TIP: Due to its strong adhesive strength, the film should only be applied to intact paintwork. For old or weathered paintwork, it is advisable to freshen up the area with a polish beforehand. To remove, the film should be heated with a hot air gun - this reduces adhesive residue (any residue can be removed with the KRS-1588 eraser).
