Well, it may now be due to the experience, but the film was a perfect match, settled after the first Anpassversuch (about 2 cm were glued) Remove to correct without damage again and could then be brought up without bubbles. Toll is the additional checkered upper protective layer that protects the film surface during winding and is only recently withdrawn.
Only the manual leaves much to be desired: Yes not the foil from the top on a train "anpappen" but deduct 2 cm first carrier sheet on a short edge, align the film and first stick with the 2-cm strips. Then you can correct. Then draw bubbles pushing with a credit card while slowly peeling off the support film, the film.
