It's no different regarding scratching/slashing of convertables. That used to happen a LOT but now it's not as often as the novelty has worn off somewhat. And cars get scratched and keyed all the time. I imagine having a panel replaced or multiple panels resprayed would cost a lot more than replacing some fabric of some kind. It could actually be made stronger than aluminum panels if they use carbon composite weaving or kevlar weaving in it too. Think shopping trolleys for a moment. The slightest litte bump and your paint needs work. Slight knocks and bumps with this stuff would just bounce right off! painted steel/aluminium isn't very resistant when you actually think about it... It'd also resist hail damage I would imagine. It takes 2 hours to completely cover a whole car - how long does a full body respray take? I actually think it solves a lot more problems than it causes. Like the engineer in the video says, panels don't have a lot to do with safety any more.
Great idea! but god it looks ugly is some areas, especially when the doors open! when the head lights open and the guards move thou that was niceeeee lol I get what he's saying thou, the exterior means dick when the crash energy is channelled threw the chassis, open mind ness, I like it
