Similar to these wheels:

Ok....I think I've got something for you. My Super Ram is done in a similar color to that....although I wouldn't say it gets super shiny in direct sunlight but notably brighter than when it's not in direct light. There's pics of my engine on my company website in the Past Projects section. If you want closer pics let me know and I can take some tomorrow for you.
