Something that really helps when working on cruisers is that wet, bunched up aluminum foil works great as a cheap way to polish chrome. Keep rubbing and the water will turn black*- that's your polish that gets rid of the rust spots. Once you're done, wipe off with a damp rag. Your Ross doesn't look like it has any deep pitting, so you should be able to get a good shine.

*Your hands (especially under the fingernails) will get really dirty doing this. If that's a concern, try latex gloves.
