My take: Ride as is if you can stand it, but there’s no wrong answer.
I powder-coated a Motobecane of similar age and I don’t regret it. The original paint job with hand-painted details must have been great, but decades of sun, rain, and neglect obliterated it. Restoration would have been starting over from scratch so I sandblasted and turned it into an electric blue beast of burden.
Somebody else can restore the original paint job 50 years from now. I’m just keeping the frame safe for them until they’re done being born and growing up somewhere. It’ll be waiting for them when they’re ready.
That multicolor combo is amazing! Makes me wish I had more separate parts to paint when I coated mine.
