Not the way I thought a golf ball would damage the truck, but...apparently it got loose in the back and rolled down beside the plastic cover and into the well. And apparently when someone tried to lower the gate and felt resistance, they kept pushing until this happened. I will likely have to remove the lower gate, but can I just "crimp" this back, sand it and repaint? I'd prefer to DIY this instead of taking it to a body shop, if at all possible, and I certainly don't want to outright replace it. Doesn't have to be absolutely perfect, just not as noticeable.
