are you trying to figure out how to remove it or what?
If so then the easiest way i've found it to remove the wheel well liner and you can get to the back of it from there. I know it has some pressure clips to release from behind and i'm pretty sure double sided tape on it as well.
as far as painting, you can use krylon fusion on it. made for plastic and no prep/primer needed. just clean it and paint.
