@forzanerazzurri so go for it: hire a lawyer and sue the bastards. Join a class action that is too late, sue the bastards, and lose. Might as well keep your car looking like crap the whole time, too, so that you can point to what a crappy paint job you are suing over. That'll make you feel better waking up each morning for months/years going forward.
As I said, if you love the car but got stiffed with a poor paint job, then a repaint is the only option: get everything out of Kia that you possibly can (or are willing to hassle for), and make your car as perfect as possible. Turn your lemons into lemonade and create a totally unique Stinger; wrap it, maybe. The options are almost endless and the results are amazing; and, done by the right sort of pros, are warrantied far longer than a Kia paint job. And also, if done right, will maintain or even increase the resale value of the car. (If the plan is to keep the car for many years, this is a pointless factor.)
