Previously ranted about in another thread, I'd bent my tailgate by stepping on it too hard, in just the wrong spot. With the plastic panel off, what appeared to be a very slight bow in the tailgate manifests itself as a sharp dent. I straightened it all up pretty well with a big clamp & some 2x4's. Man oh man, is that metal THIN!
Also it's amazing that the plastic shows no damage at all, considering the shape of the dent.
Note that the top rail of the gate is still perfectly straight, and from the exterior the gate only shows the slightest bow in it at the bottom. It's all but invisible and I didn't want to risk kinking the outer skin trying to straighten it any more.
I'm going to reinforce the gate, but right now I'm still considering just how to go about it.
