I have decided to install air horns on our two boats (Grady and Luhrs), replacing the small electric horns originally installed which generally last only a couple years. I've been searching for stainless steel horns but not having much success finding any. They seem to all be chrome plated -- some unknown metal but many brass. Am I wrong in thinking the chrome plated brass will look like crap after a couple years in a salt water environment even if kept clean?
