Can we assume that you are talking about rally wheels? As TazJr stated, the "proper" color is Argent silver. You can get it from any repo house but it will run you $15-$20 per 12 oz spray can. Then you've got shipping/handling on top of that. Your best bet would be to try and find some Krylon Dull Aluminum. It's extremely close to the Argent silver and a bunch cheaper. I believe k-mart and Wally's both sell Krylon. 2 cans will do 4 rims. I've tried the rally wheel paint that Auto Zone has and it is to dark. You may have better luck. Jim
