I checked with Kirk Evans who painted the car and here is what he wrote:
That is fortunate. Let me see if I still have some paint. If it were here, I would use an airbrush to fill the clear and blend any color into the deep area then fill it with clear. No way to get a perfect match that way if the paint is damaged but a lot of times tiny flaws are really not visible to most people. You will always see it because you know where it's at.That is a very high metallic color. What the original customer wanted, would not have been my choice because of touchup.
