Same problem with the Plus 8: I had the film replaced once, but the drivers side is now as scuffed as it was a couple of years ago.
I am tempted to take the film off, use it to make a template and then buy a length of the film and then replace the film every year..... My son Andy has experience in applying colour wrap and said that on a nice simple flat surface like the running board it will not be difficult.
I've also considered fitting tread rubbers, as we had on the Roadster.
