Talk with a paintless dent removal guy... they are miracle workers. There was a similar crease-like dent in my wifes' door that someone left a note for as well (wow!), and autodentist here in Ottawa made it disappear 100%.
They usually do airbrishing for paint chip repair and it looks great, no bondo/filler, and you'd be surprised how inexpensive it is compared to a body shop (not that you care, it's not your $, but regardless of price it's a great place to try!).
