What we do at the factory is after drilling a hole in the cored
area we mix a little dab of 5 minute epoxy on a small piece
of cardboard. (use a popcicle stick).
Then we use a Q-tip to lather the epoxy into the hole.
After about 20 minutes you can run the drill thru again.
I don't know if it helps. The balsa core does  seem to soak it
up. It sure makes us feel better :-)

Then bed with boatlife caulk as you would normally and tighen
properly.

In about 15 years the caulking will in some cases have shrunk and
cracked. Consider re-bedding before any water damage can
occur.
