Take a piece of dental floss and run it behind the letters. It will cut through the tape that holds the letters on and not break the letters. Getting the left over glue off is more difficult. I've heard some other guys talk about some type of goop remover- but I'm not exactly sure what that is. I used hot water, Tuff Stuff cleaner, Meguiars Bug and Tar Remover and Megs Paint Cleaner. Just make sure you use a soft cloth, like microfiber. Anyone out there know what the goop remover is called and where to get it. Removing the letters takes about 3 minutes. Getting the goop off took me 30.
