Though I am loathe to paint a bike, the paint damage to the Peugeot will be extremely difficult to touch up well. And, if not done properly, the result will look like a disease of some kind. Too many damaged areas. Were it me, I would protect the bare spots until I got around to a full paint job. That has always been my plan for the Legnano but I know that I can paint it anytime as the bike is not showing any surface rust...
You will love the PX10, at least I love mine...
And my
first PX10 sported horrible paint, so I painted it with a brush...
