Alan (or anyone),
Do you have a guesstimate (re-chroming cost)? On my 36-year old
boat, I have several 'perfectly good' pieces of
equipment (winches,
cleats,
ports, etc...) where the old plating has long worn out. After I paint the
hull, the shiny bits are next.
I'm pretty happy (for now) with how the rustoleum came out. I wouldn't use it anywhere substantial (like you say, I expect it to wear easily), but it took something (hinges) that was eye-catchingly bad, and made it into something that you don't notice at all. I certainly wouldn't recommend it for perfectionists who want their boats to look showroom.
