Replicating weatherd, bare aluminum?

[Ben]

Just wondering if anyone has any tips on getting a realistic, weathered finish on bare aluminum. In this case it would be the intake side of a turbo housing. It just doesn't look right in the bright silver that the "aluminum" paint produces. I was thinking of dry brushing some flat white on it but wanted to see what you guys think first.

Try just hitting that silver with some dull coat.
