My Honda nuts have 'seen a bit of action' with tyre changes, and Honda changing brake pads, so there are chips in several of them.
I recently had my Storm alloys refurbed, and when replacing the nuts, I gave them a clean up with Brasso - most came up a treat - no corrosion - just the chips (nothing I can do about that).
I was looking at the S2000 black option ones, but have decided to stick with the originals, for now.
I was more thinking aftermarket locking nuts, I have bought ebay ones in the past for about £30/£40 but they do perish after a few months.i didn't know if I bought some rays nuts(eg) for a higher price if they would perish just the same and end up being a larger waste of money.
I have the Rays wheel nuts on mine. They are duralumin nuts, not very durable in my opinion. I would go for some floating lug nuts if possible, but it depends on your budget and the design of your alloys. I think the Project Mu Super Lock Nut 7 are quite cool
