Great work as usual. It looks like you are just a short polish from finishing on the lips. Personally, I really like the bead blasted look on the centers with possibly just a seal coat to keep them from showing corrosion too soon. Nothing wrong with a powder coat black or other color on the centers, though.
I did see a set like those with red powdercoat on the centers on a red car. Still haven't decided if I liked it or not.....
