Very nice Mike, I bet you could sell those caliper logo's. I did mine subtle too. I used Rustoleum Hammered Paint. Its a cross between gray and copper and it has a metallic look to it when it dries. SO far I've had no peel issues at all. I do them every year before Carlisle and the last coat had a real nice shine to it. I did my wife's car two years ago with the same paint and they look good as new after almost 15,000 miles.
Your's look great. Like that decal too. Subtle and nice. Now its time for a set of wheels.
