I ordered the Mopar Winch Plate for my 2021 JLUR with factory steel bumper. In addition to the winch plate and hardware, it came with an extra package in the box which contains some clear (I assume paint protecting film) and a long piece of foam with adhesive on the back. Does anyone know what this is for an/or how to install it. There is no mention of it with the provided installation instructions and I've scoured the web and these forums looking for answers. Any help is appreciated. Thanks in advance.
