Like with mine i told them i wanted a sticker that said:

"(arrowhead) GRAND PRIX (arrowhead)"

When they make the sticker they make it as a "whole" so you dont have to "piece" anything together, so everything will be in a straight line.

they will make the sticker for you, then you windex the window make sure theres no debris on it before you lay it down, also DONT get the back of the sticker wet(while the paper backing is still on), pull the paper backing off then lay the sticker down(i made about a 1/2" slit in the bottom middle of the sticker and at the top so that it curves with the window, then you take a credit card and smooth out everything from the INSIDE OUT(any little air bubbles just take a needle and poke them), then pull the top layer off and your done! lol

Very simple procedure...

Its just like a regular sticker, no need for goo gone or anything like that just pull it off when you dont want it anymore.
