Sealing keelbolts or filling the holes with anyting is more likely to
accelerate crevice corrosion. Any attempts to protect keelbolts needs to
center around keeping them bone dry. You sure do not want to seal in, or
encapsulate any moisture!

Wow! My boat had this but nowhere near as pronounced. It shows itself
as a pink “ooze” coming out of a couple of minor blisters below the
keel-hull joint. I have been putting about 3 gallons of antifreeze in
the bilge each winter to prevent any water that gets in the bilge from
freezing, hence the pink color. Hopefully adding the antifreeze has
prevented the problem from getting worse.
I do intend to undo the keel bolt nuts, seal around the keel bolts
with butyl rubber and torque the bolts. Anyone have any thoughts on this?

Good morning all. Several weeks back there was a discussion
surrounding issues with bulging keel castings in colder climates.
Been meaning to post some photos I took awhile back, here they are:
