I think when you get a sticker and replace the windscreen, the window guys put it on the new window . . i think, from what ive been told.
Dan, i like your thinking lol. . rip the sticker off and whack it in the boot haha when you get pulled over and mr plod asks you about it just open the boot, show him and explain that the sticker wasnt any good on the window as it didnt go with the colour theme of the car haha
