oh, and be careful with the volume of epoxy you mix up in one pot.
larger amounts kick of pretty fast and REALLY hot!! Ask me how I know
that! That same boat had wet deck round a 4" vent somebody installed by
simply jig sawing the opening and caulking the vent down, the moisture
got pretty deep too. That was big void and I mixed what thought was an
appropriate amount. that stuff kicked off and almost burned my hands it
was so hot I had to drop it and it melted the plastic container i was
using for a pot. you could mix smaller amounts in separate pots to
avoid this issue but, it made the deck really hot too. I think the
amount I mixxed would have been about a 3rd or maybe a 1/2 of one of
those plastic quart containers you get at the deli. (we do dumb things
sometimes... this is how we learn!! LOL)

Randy,
When I rebed my chainplates 2 years ago – had to dig out the wet balsa
and replace with epoxy using the chainplates wrapped in wax paper as
plugs / forms – found the chainplates themselves were quite corroded
on the back side which was against the bulkhead. Several of the
stainless bolts were severely rusted and the chainplates had tiny
cracks fully through the metal at the bolt holes. Had new chainplates
fabricated.
As you are in fresh water it may not be as much of an issue, but if
your boat lived much of its life in saltwater previously, there may be
damage to the metal. Make sure you closely examine the chainplates
for any corrosion!

Thanks Dennis (and Gary and Sam). Let me see where I stand on Tuesday
- I may be ready to epoxy if I can do the bent nail and acetone thing
tomorrow. Let's call or text on Tuesday.
Gary - my chainplate covers are aluminum and still in good shape, just
needed a really good cleaning (probably 44 years' worth of various
sealant jobs built up on their undersides).
Sam - yes my chainplates bolt to fiberglass "knees" tabbed to the
hull. And the chainplates and knees are in good shape - no sign of
weakening from exposure to moisture. I just want to make sure I do a
proper job of sealing it all up so I don't get more coring in the deck
going forward. Unfortunately it looks like my boat's previous owners
didn't do a proper job (e.g. per Don Casey's prescriptions) of keeping
this area sealed, and a little bit of coring occurred. The starboard
side was all gooped up with clear silicone, and the port side had an
ineffective bead of white caulk around the edge of the cover, and both
sides had hard-as-rock probably original white-colored sealant under
those other sealants.
I'll be using polysulfide (Life Caulk) per Don Casey for the
re-bedding sealant.
Cheers,
Randy

Randy,
You're on the right track. Wish I'd known you were doing that, I
would have stopped by and taken a peek. I'm back up in the mountains now.
If it was me, I'd remove the wet core as far back as I could with bent
nail, etc., dry it with acetone and/or heat gun, tape the area, inject
some neat epoxy until it was level with the deck, use bent nail to
agitate it then quickly suck out the epoxy. That will coat the exposed
surfaces so the thickened epoxy will bond better. Then I'd inject
thickened epoxy, let it cure and re-install the chalnplates. Don't
forget to chamfer the hole so the bedding plate doesn't sit down on a
square edged cut.
I'm headed back down to the airport Tuesday afternoon. Got to pick up
my ski buddies Wednesday morning. I might be able to swing by the dry
storage on the way.
Dennis C.
