good question. Might wanna try just your fingernail and grabbing the ege of it and just atking your time. You might also could try some adhessive remover to break the bond or at least lubricate it to make it easier to comeo ff.
you might run into a problem depending on how long the vinyl has been on the paint.
If its been on for awhile you could have some nice paint fade on the rest of the car and under the vinyl could be a brighter shade of your paint.
