Coverage and how to read this overview

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.

POST 1 / ORIGINAL POSTEROriginal post

Ola, I have 18" sport design two piece wheels a la GT3 on my C2. I clean them weekly and they are pretty immaculate but this week I have noticed a white patch on the rim near the tyre which doesn't respond to the normal vigorous sponge. Looks like a bit of corrosion but it wasn't there the week before and I am a little mystified! Any suggestions on getting rid of it? I know there are all sorts of things you shouldn't do with these diamond cut wheels and elbow grease has no effect...... Many thanks.... Mark

POST 2Original post

It's almost certainly the laquer lifting, water getting in underneath and the start of corrosion; a very common problem with diamond-cut rims [ ] I've never really found a good way of effecting an lasting repair, but you could hold off the need for a proper refurb by removing the lifted laquer very carefully with wet & dry paper, lightly polishing the corrosion out and then re-laquering. Expect to have to do this again (and again, and again)!

POST 3 / ORIGINAL POSTEROriginal post

Thanks for the reply... The thing I can't work out on these wheels is that the spokes and hub are painted and lacquered whereas the separate rim appears to be unpainted which is why I am worried about getting going with some sandpaper....they have a machined appearance and I think I would do a terrible job...looks like something for a professional...

POST 4Original post

I know what you mean, but the laquer is there. I have exactly the same problem on a set of BBS RXII wheels & a quick rub of 800 emery in the direction of the wheel rotation is all that's needed to remove the laquer. I know it doesn't help, but several people warned me off the Porsche 2-piece wheels before I bought my 911, saying that they were known to corrode very easily & need frequent refurbs as a result.

POST 5Original post

Seconded. Refurb options include paint only, paint & laquer, or anodising for the rims.

POST 6Original post

Anodising is probably the most effective, long-lasting option.
