The auto body artist I took it to says he's going to straighten up the rear wing. I've seen the "before & after" album he keeps. It's possible. Though, I sure don't know how it's done. The cat's good!
"Artist" is the key word: it takes patience, skill, and an artist's/craftsman's touch. Nowadays, many body technicians don't fully develop those skills and artistry, simply because it's not economically feasible to do a lot of hammer work in a collision/insurance settlement shop environment.
Back when I was in high school in the late 1960s, my dad brought home a book that had been deaccessioned from the library where he (and now I) work. It was a late 1940s automotive body work text book. The techniques are still mostly valid, of course, but the photos of what shops would repair back then are mind-boggling. Nowadays, if a front fender has much more than hail damage and bolts on, it's tossed and a new one put in its place. Kinda sad....
