Re: "The chainplate will buff out and probably be okay"
"I know from experience that it will buff out and will probably be okay."
Niiiiiice..... Why inspect something if you don't know what bad looks like when you find it? Besides, who needs to "buff out" something (a cosmetic fix) that is behind wooden panels anyway?
My chain-plates are all kinds of bad. It's the next big project for my boat. I'm contemplating making a home foundry and casting my own out of bronze....
