not easy to apply

The film is relatively stiff. This produce even the tiniest speck of dust under relatively large bubbles.
The first attempt to raise the film without bubbles resulted in an ugly bubble carpet despite meticulous cleaning beforehand.

Because I could not look at it, I've tried the wet-Aufziehmethode, as used in InvisibleShield.

1. The film gently pulling back and soak in a tray with detergent-water solution - so for about 15 minutes. The film in this cleaning solution, wash the dust from the first attempt is gone.
(This step is not necessary, of course, if you want to try it out directly with a Nun film.)

2. Add two drops of detergent and about 50 ml of distilled water in an old small spray bottle and mix well. The spray bottle previously cleaned thoroughly with detergent and rinse afterwards with distilled water (iron water).
Where to get the spray? Had I not from Aldi with deodorant in there.

3. Clean the screen carefully.

4. All ports and slots etc. tablet with tape masking tape without the device's screen.

5. Check the screen and the back of the film evenly wet with the spray bottle.

6. Slide rinse under running water and place carefully on the screen.

7. Wipe with a credit card or the like, the water-soap mixture from the center of the sheet to the outside - carefully! Here, the squeezed out around the edges of the film water immediately wipe with a clean cloth. Otherwise crawling yet what the tablet.

Now I have only three tiny bubbles under the film, but they are so small that they no longer interfere ..
I will soon report on how the long-term effect is. Perhaps the film falls after this treatment from or something ....

Until then, there's first 4 star :-)
