Decided due to very positive reviews for this film me. Contrary to the assembly instructions I have the sheet previously cut with 1 mm undersize to measure (this work please accurately) dry stopped and when it suited to work with a lot Wasserspülimischung on the window, on the slide inside and from the outside. Now, the film floats on the window. After doctoring out from the inside out, the film is a very short time without bubbles at the window. According to the manufacturer, the film now needs a few days until you finally liable. If the result remains as it now is I am very satisfied. Should it get worse, I will contact you again. But with this foolproof assembly, performed on three normal windows alone, I did not expect.
