I was poking around for any rust hiding. Looking at the tailgate, it is totally covered by plastic on the inside face and a strip of cladding on the outside. I figured this must be hiding some nasty rust at the bottom of the gate. I had a magnet that I was using to pick up screws and when I went to stick it to the tailgate panel, Nothing. Wth? Its not metal? I'm kinda glad as it can't be very rusty then but I'm surprised. Couldn't find any info about it. Fiberglass? Mid-gate too? Is this all newer trucks?
