Where's the RUST? I didn't see any.
Under some conditions, rust will "grow" out of a tiny pinholes or scratches in the paint and spread across the surface, looking much worse that it is. A stiff nylon brush sometimes works to get most of it off. I use a dental tool to pick away small areas of rust in the scratches and chips then try to match the paint and do a light touch-up.
If there is heavy clearcoat or paint, 4X steel wool or super fine Scotchbrite can get rid of some of the surface rust, then use rubbing compound to get rid of the scratches.
If the rust has spread under the paint and lifted it in small areas, I use a dental pick to remove the paint flakes and rust.
Beyond that commercial rust remover is the next step. I use Evapo-Rust but there's other brands on the market. For rust around cable guides, I scrape off the excess then insert a Q-Tip soaked in the stuff.
Wrap it in some plastic wrap and leave it set for a day or so. You may need to repeat the process several times. Use cotton balls the same way for larger areas.
