It’s the same paint they used on the TV show the Dukes of Hazard. Not only did that car never have a scratch in the paint, the fenders would straighten themselves out between shots and the car would jump on command.
You just have to love Hollywood. Even though the movie Unstoppable is based on an actual event, Hollywood had to jazz it up so much, that the facts get lost in the fiction. But it is a good movie, if you can look beyond the impossible feats.
It’s referred to as “self-healing steel envelope” and was developed shortly after that bionic dude in Million Dollar Man. Besides, a lot of Hollywood productions stand with one foot in the parallel universe.
In any case, I just sit back, relax and marvel. If someone were to come along and offer me a whale of a deal on eBay, I’d probably go for that, too.
