It was less expensive to replace her hood but this is not true in all cases. All minor fender benders are expensive. Paint work is expensive. If a rubber bumper/facia is involved you can count on $2K +
I'm not saying that aluminum is less or equally as expensive to repair, just that it can be repaired by your corner BS.
Spray-on bed liners stick to paint for the most part, it really does not matter what is under the paint.
And spray on bed liners do not prevent damage other than scratches in the paint and surface rust. A spray on bed liner offers no help with the same type damage shown in the Chevy commercial.
I currently have a Toyota branded slip in bed liner, I thought I wanted to get rid of it and go with a spray on again but 10 years later it is still doing fine. ;~)
I had a spray-on on my Silverado. It looked like black wrinkle paint. And held up well to wear. AND it stayed cool in the dead of summer, it never go hot. BUT it seemed to evaporate... it slowly disappeared/ became thin, and not from abrasion. It simply developed thin spots between the wrinkle high spots and the paint began to appear again. These spots seemed be where it had the most sun exposure. BUT it did last 10 years.
