Difficult to judge but it might compound out? Need to be careful not to compromise the lacquer. The wheels are diamond cut, as I understand it they're sprayed gloss black all over then the faces are milled - the silver is the actual alloy of the wheel - then lacquered. You don't want penetration through the lacquer and especially not over the silver, as corrosion will quickly set in. I lazily used the wrench in the factory tool kit rather than look for a socket and have taken the paint off the bolt holes.. twice!
