Damn fine job! Dying to hear the details on how it was done, and comments from the framebuilder.
You should paint over it else it'll rust. Maybe for once I'll advocate a clear coat, at least for a season. Everyone believes it'll have spider rust under it, now would be a good time to test that theory! You can always go back in next season and paint it over.
