A few people, there is always that disregard the instructions for fitting and then not get a satisfactory result out ...
A key point is that the windows are cleaned. The films can be good with a cutter to the desired size trim.
What you absolutely need to humidify a spray bottle. I had bought one from a well-known furniture store for 1.
Spray bottle with water and few drops of detergent to fill.
Pull off the carrier foil. The thus revealed smooth side with the spray bottle spray. The window also spray. For me it worked best when the window was really wet, but only a few large drops formed, running down the pane.
Press sheet to the window. It was super easy to slide the foil to the right place. In an emergency, they can be even again relieve us new push against. Press with a doctor or just a credit card, the air bubbles from the inside out. It is also water that is between the film and window pane, pressed out. Best remove the excess water with paper towels when pulling. If one looks very obliquely to the film you see which still bubbles must be removed.
I have stuck with me four windows and it was within a couple of minutes when I knew how to do it. The time now have passed a few weeks. The film holds bombproof. So normally we see absolutely no air bubbles with me. If you close it with the eye off - 15 cm or less, and at such an angle as possible watch it, you can make tiny bubbles. For this I would have been but the head almost to the disc over, otherwise you can not see it.
I am very happy with the film and they've also like a friend recommended. I just wish I had bought earlier times as a window film.
Looks very good - from the inside and from the outside. From light ago I can not notice any difference in brightness.
