I've just bought a 2005 C55 in like-new condition with very few miles on it (for owners of this model, you don't want to know how much I paid for it). In any case, the one disappointing aspect of the appearance is that the paint has worn off the lug bolts, and they're starting to show rust. The weathering may be due to the fact that this car was stored outside frequently with a car cover to protect the paint, but unfortunately it didn't cover the wheel hubs.
It surprises me a little that these lug bolts seem to have been protected only with paint -- even my Mini's lug bolts had been anodized. I can always paint them over with some bright silver paint, but what are the alternatives? Does anyone make an aftermarket chrome or even black lug bolt that will fit the AMG wheels?
Thanks

Re: Rusting lug bolts

It's a "German thing" I think.

From BMW motorcycle experience, it's clear that some regulation must have come into effect in Germany regarding environmental release of chemicals, and bolts seem to no longer be as corrosion-protected as they were in earlier years. Lots more exposure of bolts on motorcycles, of course, and lots of concern about how things look.

Maybe some WD-40 or something on the bolt heads (not the threads) could help.
