I have found is you polish aluminum to a high gloss finish it seems to seal the metal and it keeps it’s sheen with very little cleaning needed other than a regular wash and polish like you would do for the chromeI get the polishing part, but then I have to do it every few months as the aluminum is being taken down to bare metal. the paint will seal it for year as long as I don't damage it.
