Hopefully someone out there has some insight into how to get the cover off so I can get at the bumper frame underneath it which is collapsing from corrosion. I can see screws going from the top down into the cover but can't get at them because of a body colored 2" wide piece of trim that wraps around the back of the car under the tail lights and hatch. How do I get that piece of trim off? Thanks.
