Leading evidence: 'Use razor blade' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'good idea' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Clean heck out of them in no time' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Probably a good idea so they can have many years ahead of them...

Suggestion · Original poster
I removed the wheels to clean the inside and found what appeared to be spots of oxidation combined with brake dust on one of the back 10"wheels.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Just bought a low mileage 2000 C2 coupe with 18" 10 spoke Sport Design Wheels. I removed the wheels to clean the inside and found what appeared to be spots of oxidation combined with brake dust on one of the back 10"wheels. I was able to scrape it off with a razor blade but still doesn't look good. Question, does Porsche paint or clear coat the inside of the wheels. If I was to sand it smooth what should I do to refinish.? Any wheel experts out there. Thanks Jim
You can always have them refinished to bring them back to new again...
Probably a good idea so they can have many years ahead of them... Remember they are a solid 15-years old now...

Thanks for the offer but the fronts are flawless, just the inside facing the rotor on one wheel has that problem. Hope to fix myself. Is it clear coat, paint or something else?
I googled Sonox, looks like good stuff. Not sure it will resolve these spots inside the wheels. They looked like raised oxidized patches mixed with brake dust. I used a razor blade to scrape them off. I'd love to know what the inside of the wheel is coated with. I would sand the spots and repaint or clear coat the inside.
I recently had mine refinished and did quite a bit of scrubbing prior to this. Since the back side of the wheel is just machined aluminum, it must have had clear coat on it originally. Mine are now powder coated with clear.
