Hopefully, no one throws me off the forum for this.
When I bought my car, the inside of a couple wheels were somewhat stained from brake dust in a few spots. The OEM paint surface was cosmetically damaged. I tried Krylon rattle can silver, since, if it happened to not match, it is easy to remove without damaging the OEM paint. The Krylon matched near perfect. I simply fogged the paint out when applying, and it was near not noticeable. If the wheel is off and you look at it, you would not see where I painted it, until I very closely pointed it out.
I cleaned the OEM surface and did NOT scuff. I appled the Krylon over the OEM shinny surface. I wanted to go back to OEM if the Krylon failed. Over many years, the Krylon still is in great shape.
