Wanted to build me with these parts a mirror and have a part ordered for testing. But even after I wiped some fingerprints with a cloth, the surface was covered with very fine scratches. If you have to clean this film regularly (as a mirror), I can imagine that it is very fast blind. Therefore, absolutely not suitable for permanent use. Although intended primarily for car mirror, but even there I would not use. Over time, even here, the surface will suffer significantly and allow no more looking back. Is not absolutely level the ground, ddie surface distorts the reflection clearly.
