Great photo of what is underneath the rust....once it appears if it is not very corroded a light clean and polish will make it less noticeable. When it gets to this stage only options are re-chroming (expensive!) sand primer and paint to match frame or sand and clearcoat.
I guess you could also use a metal foil tope that AC contractors use if careful with the application. I have used it as a chain protector on the rear stay of a few of my bikes and it looks like chrome if applied

The surface will need to be sanded completely smooth in order to have a maximum positive effect...it also wrinkles quite easily.
It does wrinkle if one is not careful.
