I did the same thing with the screen protector. I bought one off of amazon before I even got the truck. I peeled the factory film off and put the screen protector on, lol. But I'm just paranoid, I do the same thing with new phones or tablets. I'll put a case and screen protector on it before I use the device. If yours is scratched up that bad though. I'd bet you wiped it down with a cloth that had dirt or something course on it already. I can't imagine your finger scratching it like that. I doubt a dealer would warranty it, Might be worth a try though. If not I'd try the plexus. It really does work well on plastic and it won't hurt it. I've used it on TVs and computer monitors. I keep a few cans of it and use it on anything plastic. I wiped down an entire Polaris RZR with it before I sold it before. Made it look brand new, lol
