They did all the aluminum on my 65 Dart GT. Not sure what their length limit is, but long pieces included the finder trim, grill, candy canes, hood trim, and the trunk trim between the tail lights. I didn't take any closeups of the trim, but I can tell you that the quality of the polish is very important. I had it looking like chrome before it was dipped. After anodizing, it was not nearly as bright.

A friend of mine has the same car. He chose to leave his bare. It shines brighter that way, but there is some effort to keep it looking good. He just hits it with a product from Chemical Guys and it brightens right back up. Less work than I would have thought, but his car doesn't get out much. I also understand that the anodizing is very hard and protects the soft aluminum from fine scratches. I guess my advice would be if you want it to look original, have it anodized. If you plan to drive your car a lot, have it anodized. If you want it to look as bright as possible and your car is never going to see weather, then leave it bare.
