Photoshop help: 1966 Valiant Grilles. Powdercoat? Re-anodize? Polished Aluminum?

no problem. Always nice to see the possible end result before you actually have to do anything :). I like the originals also. The more i look at the image with the grills in different colors, the more i like option 1, simple but not straying too far from the original.
Glad i could help.
