That bike could be greatly improved by dabbing on some phosphoric or citric acid ?.
And careful rinse off and then a light wipeover with linseed oil.
(gently removes the bulk of the rust, and puts a shine back in original paint)
Or even just a wipeover with an oily rag.
But that precludes any future gentle rust removal.
I know some folk like the rusty crusty look, but when it has sooo much potential as an original paint bike ...
