I have found 1 spray can paint that is an absolute match for the color. The trouble is that it is not very tough and you NEED to clear coat over it or it will fail with exposure to fuel. It is a Valspar brand plastic paint. The color is an exact match, and I have found it at Lowes. I have experimented with other clear top coats, and have two that I am considering. I have top coated immediately or else wait a month and use a Dupli-Color automotive clear lacquer. This must be put on with several coats, the first two or three must be fairly dry. Then I add a fairly wet coat, then let it dry. Wet sand with 600 and 1000 and polish up. It gives a great look, and I have had reasonable luck with the durability. I am also going to purchase some automotive catalytic acrylic enamel clear and see if I can top coat without having the base surface crawl. I know it is a lot of work, and not what you are looking for by using a spray bomb, but that is what I have found. I have also used Rust Oleum Cedar Green, and then bake it in a hot room for an hour. This color is a good color, but a little too green for an exact match. It is quite durable as it, and can be clear coated with their clear coat also.
