You can restore something 100 times, but it's original once.
It's gotten really picky with vintage bicycles- some are worth more all rusty if there is a hint of the original paint. I just got a Rollfast bike with a skip tooth chain. It's got a decent, years old, not professional, re-finish. I'll probably do some touch ups and go rat rod with it- new wheels etc, because it's not too original.
