Keep it that way, less people looking at it with an evil eye. Get all small jobs done at once from Insurance, it makes it easier for you, dealership and Insurance agent. If the whole bumper needs repainting, well, be prepared to be without the car for 1-2 days, if they are busy.
If you want full bumper replaced, make a large hole, say something hit it, colour the surrounding area blue. I like blue. It works.
