C. Vaselaar:
I see you joined the forum in June, and just now made your first post. May I welcome you here, and also mention that had you posed your question in June, your wheels would have been painted by now!
Seriously, welcome, and don't be shy.
I used the Moss paint, and it looks as close to the original as any I have found. Some of the paint is too "shiny", but the stuff I got from Moss had the proper "Metallic Grey" look to it.
It's hard to describe a color verbally.
