The installation instructions are good, the tip with the water should be observed! Additional tip for the separation of adhesive and backing film:
1. A smooth surface wet (eg table) then the film with the mirror side put it down so that the water developed an adhesive effect. Then pull off the backing sheet upward. The adhesive side is then exposed, without the risk that the ribbon creases same and stick to itself.
2. Only with total wind run, because the mirror film is really sau thin and when the adhesive side is touched himself over.
