Remove any oil from the surface with an alcohol swab.

Clean the work area of dust before applying.
Unused or extra films can clean dust effectively before applying.

Tap water may cause clouding.

Applying films under a bright light is recommended for accuracy.

When removing a film using a tweezers, watch your pressure as it can leave a mark on the film.

First applying films to parts that are prone to scratches, such as case back can make the process easier.

When applying to the case back, bezel and glass, it is better to apply from outside to inside.
For example, if glass film is applied first, then it can come out of place and/or air bubbles can form inside it in the process of applying the bezel film.

When removing doughnut-shaped films such as bezel or case back films, it is easier to remove the films within them first.

If stretching is needed, do not stretch films before applying. Apply and then stretch.
Beware that, once stretched, the film is difficult to restore to the original form.

Due to the curved nature of crown guards, films for these parts are prone to peeling.
