From this slide, I can only advise - it may be extremely scratch-resistant, the adhesive side is unfortunately also extremely Empflindlich !!! The "glue" the film has to be done under absolutely dust-free conditions. When attaching the film a mini-bubble has formed - after very careful lifting the film emerged after more small bubbles in the border area, which can no longer be removed because the Adhesive side was contaminated directly - although I was extremely careful! Purify the film is impossible!
