I fixed mine about 10 years ago and it has remained completely fixed,
despite a few incidents of groundings. I cleaned out the joint mostly by
using a wire wheel chucked in a drill. That dug a channel all the way
along the length of the joint on both sides and around the leading edge.
Then re-torqued the keel bolts to spec using a long handled 3/4 inch
drive torque wrench and a variety of extensions, adapters, and sockets
that I collected from a number of sources. I got the now dis-continued
torque wrench from Harbor Freight for around $100. The rest of the
sockets and stuff was a few hundred dollars. Heavy Equipment and truck
mechanics use this big stuff, so ask some of them where they buy tools
besides Snap-On, which is scary expensive. I know I got some of the deep
sockets from NAPA autoparts. They sell them individually, which is good,
because those big deep sizes aren't cheap! My boat has 3 different sized
bolts.
Following re-torque adventure, I used a brass brush dipped in
un-thickened epoxy to clean and seal the exposed metal and fiberglass.
Next step was to fill the channel using Epoxy thickened to the
consistency of peanut butter. Then I used a sander with 80 grit paper to
clean an area all the way around extending about 10" above and 12" below
the joint, which I then "primed with the brass brush/un-thickened epoxy.
Followed that with several layers of fiberglass cloth soaked in slightly
thickened epoxy and wraped like a bandage extending about 10 inches
above and below the joint. Re-faired the keel and applied many coats of
interprotect 2000 to seal the surface. Reapplied the first coat of
micron extra before the final coat of interprotect cured. Previously I
had tried sealing the joint with various fillers including 5200, 4200,
Marinetex, Thickened epoxy with fibers. I got to try many fillers
because none of them lasted from launch to haul out of a single season.

I just bought a 1975 C&C 25mk. It's my first sailboat I have owned. Just wondering
what is the best product to use to fix the C&C smile. Also what is the procedure to
go about fixing it?
