Numptie of the highest order
I fitted a new one a few weekends ago, as mine was starting to annoy me like jojo's, I ended up having to drill the old screws out. The new part does come painted but on my car it seems a lot lighter (I think you can just about see a difference in the pic jojo has posted) than the rear section on the same side. It might be made more obvious because my car is yellow though. I'm giving it a few weeks before I decide if it's worth replacing the rear section too.
