If I was you, I would go and have a company shoot the gun at your car in order to get the specific paint color. I am judging that the car is not brand new or has been kept in a garage the whole time. If you go to paint the bumper it will be a different color than the rest of the car due to fading.
Then go to Virginia Paint Company off of Broad....mapquest it. Get your paint, and I might be able to set you up with someone to paint it, I will contact him today to see if he is available. He painted my car and did a good job on it. Others on here can vouche. I would paint it, but I have not truely perfected clear coating and I do not feel great about clearing somebody else's stuff, until I feel comfortable with my own. However, Fiberglass bodykit work...I am damn good at.
