Rich, your entire post is excellent, but this first sentence is really great. Very concise. May I quote you?

There is no question that where you have rust, you have corrosion. Just like where you have smoke, you have fire.
I have consistently noticed over the years that where I find evident "bleeding" from thru-deck chainplates that there is usually a crack. Either in a bolt or the plate itself.
Where there is a concentrated rust spot on a piece of 1 x 19 wire, there is usually a broken strand.

I also really agree that bonding the chainplate to the hull is a smart thing to do. I know that there are many who shudder, but I always use 5200 to bed chainplates.

Lastly, I would strongly recommend that square holes be avoided at any cost. Choosing carriage bolts because of how pretty they are is really silly when you consider how much of a propensity there is for cracking to occur at the corners of square holes.
