i took the left side black strip off my car, looks way better. once you get the black plastic off. i used a razor blade very gently along to get the sikafelx as close to the paint as possible. then using the caramel wheel (available from auto paint shops) on a drill and get it off that way. You will need some prepsol and a rag of some sort to rub the remaining sikaflex off after you have attacked it with the caramel wheel.
You will need close to a whole weekend to do this properly. I dont agree with IPCOlsenVZ about the car yards doing it, They would be late 05/06 models that didnt come from the factory with this ugly black stripe.
