We have a '72. You are beating me to my planned spring project. The one on our trailer has a grey lower band and the upper portion is white. I am planning to repaint the same.
We do have a crack in ours that I will try to repair, but not having started, I'm not sure what the repair options are. I'm assuming it is a metal cover, not plastic, but don't even know that for sure yet.
