I see now how old this post was. Regardless, I polish my bikes with shoe polish. If you clean and lightly polish an older bike like these with very fine polishing compound, and them wax it with colored shoe polish, the results are stunning. Especially a black bike. Get parade gloss black kiwi shoe polish, even if you’re just waxing a clean bike. Buff it well with a chamois and you’ll be shocked how well it works.
