Kylon 1403 aluminum is a very close match for original rallye rim paint. I've seen it sprayed on original paint 71 rally that needed a refreshing.
I used the same Krylon dull aluminum on my wheels. It's a great match. Had to go to a couple hardware stores to find it.
It's hard to get paint down into the seam without getting runs so what I did was use a very small detail paint brush and paint the seam and then used the spray can to do the rest. The wheels will get rusty in the seams if you don't prime and paint in there.
