My advice to the bubbles and dust-free pasting, it requires:
Microfiber Cloth
2 disposable gloves
Make the object with the microfiber cloth dust and grease free.
Disposable gloves and remove carrier foil in half and aligning it with the object, then press down firmly with the forefinger of his left hand. Then slowly pull out the carrier sheet and further emphasize firmly to the left fingers. Then even the edges and press down firmly.
Done.
In this way I paper scraps all devices I have, it always works dust and bubble free.
I do not believe in tips with Go into the bathroom and stick there because the bathroom has mostly no proper table and therefore can not be real pasting.
