Airstream Store at Jackson Center sells rattle cans to match various colors, a little higher cost than it should be plus shipping, but a good chance it will match.
We used a Rustoleum metallic charcoal . Was an extremely close match for ours. I don't know if AS changed colors on them since yours was built, but rustoleum is pretty inexpensive.
