The provision is somewhat problematic. One must not work with too much "Spüli" because then not hold the edge. I've resorted to nem hairdryer and executed carefully blow warm air at the edges. So the water has warped and eventually have then held the edges so-so. Perfect fit is something else.
Anyone who wants to make it better: are untwist from the bathroom, door, shower hot and wait until the mirror fogged. Then the room is virtually dust-free! Someone in the Famlie is found that needs showers. After you have then optimal Bedinungen ;-)
When sticking, do not touch the adhesive side of the film, otherwise there spots and places which hold come to good. Just do not stick the whole film all at once but little by little work ... and pull off more and more from the protection of the adhesive side ... Then there is also a great result.
