Guyz you can use shampoo water while pasting it on the surface! Remember when you took your car for tinting, the guy uses shampoo water on both the surfaces and wipes it off with the so called wiper he has! Shampoo water is used because that is slipery.
Now regarding about the air bubbles automatically disappearing after some duration; the surface gets heaten up due to sunlight, so the air bubbles goes away. Hmm, its a slow process but it works!
