Sorry - Just got back to this, but you got them done?

I did the four in my boat a few weeks ago.

The Rot Doctor epoxy I have used before successfully, on my 3" exhaust transome penetrations, and it seemed to do the trick again.

I did use 1/8", a bit less actually, and used white Boatlife Lifecalk around them. Nothing against 3M, just a preference.

I'm not in the water yet, so we'll see.
