ignore catty posters. i appreciate a good paint job too. if the scratches are just on the clear coat, use a scratch remover grade car wax and lightly buff the scratches so they are smooth and clean. next just use and automotive clear coat paint pen to fill in the scratches. ta dah!! no more scratches. well, they will look better. otherwise, if you must have stickers, just ask the lbs guys in your neighborhood. they always have stuff lying around they will just give you for free!
