Your portlight replacements should look great in bronze. I have a question about bronze, it's not a little work to keep bronze clean and shinney. Is there some kind of varnish that can be applied to keep them from tarnishing? My portlights on my Commander have been replaced with bronze portholes and they tarnish in about a week after being cleaned and polished.(Thanks for mentioning Bristol Bronze they still have my Pearson Commander potmetel insignia things)
