I am way late but just so people in the future who might look here can know, Dr. Color Chip would make that area MUCH better. You can sand the roughest part down with 600-800 grit wetsanding, and cut away the pieces of paint that are flaking with an exacto. Use the squeegee that Dr. Color Chip sells and you can make the color match, such that you bumper (HokieZHP) would pass what some call the "5 foot test" where it becomes invisible. That's not to say if you have the highest standards it shouldn't be resprayed, but some people have different priorities.
