The modern techniques adhere rings to the outside and pull.   You can move the rings around where needed, and a common technique is to adhere many in a row, thread a rod through them, and pull them together.    This is done a lot in automotive repair.    My hangar neighbor did this to reshape the tip tank on his Comanche after a bird strike mangled it, and it came out quite nicely.

I think I’ve watched a YouTube video or two about someone doing this.  It was a while ago but from what I remember he took a mangled panel on a car and made it look perfect.  It was pretty impressive.
