Don't be afraid of chrome. Not all chromed horns are the same. Mine is chrome over I think brass and has been in salt spray for nine years. Looks perfect. It is a road tractor horn, and the road environment and sea are not that far apart. Road salt and sea salt work much the same.
Now chrome on top of pot metal, that is garbage. I think that may be what you are referring to.
