The paint looks pretty good overall. The blem on the down tube adjacent to the head tube is a challenge as it was touched up at one point and not very well, you will have to go and get that clean then prime to secure, then touch up.
The chrome is the real problem. The fork crown looks a bit better than the chain stays but no by much.
I think it is a what to do with the chrome situation, not respray. This is from a time where the Italians by and large got short changed by their chrome platers, I don't even see any nickel under that chain stay chrome, talk about cutting corners.

On the fork crown I would be tempted to clean it up, and paint the top of the crown only then clear coat it.
Ont the chain stays...they will be a continual problem, especially on the drive side with chain slap.
Might be a candidate for brush plating, I am not really confident on what tom advise.
Perhaps others have faced this and been successful.

As it has SLX tubing, it is from the middle 80's at the youngest. Not bad at all, but a '73 would be really really rare.
