Nahh... All you gotta do is wet them a little bit, not much just a bit. Works a treat, I used to do it with my L's taking them off all the time.
They the ones with all the little holes? theyre the best ones
spray windex or window cleaner watever over the window and wipe it in , then spray some on the P plate and stick it up, not only does stick, ***in cleans too!!!!!!!!!!!!
i keep a bottle of windex in the car... just spray it on like said above. but if you keep it in the car dont forgot to close the nozzle or you will get a flooded glove box
