putting on window sticker

just got a sticker i'm gonna put on, but want to make sure i'm doing it right first. it's one that you'd see accross the top of the back windshield, but smaller, and i'm thinking it's gonna go on the front. anyways, i want to make sure i do it right, so if somebody can give me directions on how not to screw it up, i'd appreciate it

make sure it's straight and even,spray some windex or water on the window.peel the bottom layer off and place the sticker on the window,move it around till you get it right then
grab a credit card or something and squgee(sp) the top of the sticker.for thatall the water or windex and air from under the sticker is gone.then peel of the top layer slow and make sure all the letters stay down

cool...thanks

Dont use windex , use a ph balanced soap like baby shampoo or it will loosen the glue and you may get a phenomena known as sagging sticker , this is where the decal or sticker used starts to un adhere and drop with gravity on hot days.
