my mate mike got a yellow and the car was locked up and we were watching from far away. they placed it on the outside of the window and on an angle.. after they left we walked over and peeled it off... drove it home and stuck in inside the window neatly later..
meh...
good luck with gettin it off
(oh one time the cops got out with a army knife and sliced the yellow up.. we still managed to peel it off tho )
