They sell stripe and sticker removers,,,at the local auto store,,,,
I just removed my tail stripe off the charger,,and it went fine,,,didnt hurt the paint,,etc.

They have some that are spray on,,,rub on,,etc.

They also sell a "stripe" removing wheel,,,by 3M,,,havent used it,,but might be something to think about....the wheel isnt that big,,,but looked to work great....

i put a link to you tube....which shows the wheel....
