Prob not going to fix the scratches but back in the day, 60's, I'd clean em with paint remover, spray paint the whole face and then with a 000, (didn't know 0000 existed but 000 imitated Schwinn's brushed metal finish) carefully rub off the sides and letters. It was almost too easy. I might have spread the steel wool over a flat surface to keep it out of the paint. , but don't recall. That was so long ago the only other ting I remembers is, how proud and really good at it I were. Plus, as a teen had a hel-o-lot more patience which was due to not having a job or responsibilities, I spect, then now.
