The center cap is spray painted. It was the closest I could match the powder coating with.
I put a few pics so you can see the powder coat in the sun and shade, it has decent reflectiveness. I did not put the clear coat over the powder coat and was recomended not to.
Let me know if you want a uber-close up (sorry, I saw Germany and had to throw that in), I can take some more pics over the weekend.
