We discovered  that the leading edge of the keel at the interface to the boat had some very large honey combed holes, not in the lead but in the filler along the leading edge near the stub.  We filled the holes  with epoxy (a lot of  epoxy) then filled the crack we had ground out and the surrounding area with long haired bondo, faired  the work, epoxy coated and painted and two years later still no problems.   Don’t be afraid to take a grinder and sander, after all its only lead and can be filled and faired pretty easily.

> Last haul out I had weeping from several spots on the keel. The yard suggested grinding away the spots, filling, then faring them. They said that the infiltration would spread. I had them do the work; they charged about 1 boat unit for the job. I am three years into this bottom job, and the diver does not indicate any problem down there. Of course, next haul out will reveal all.

I then took my "roto tool" and ground out a bit more of the old caulk to obtain a clean surface  at a depth of about 1/4 inch.  I then applied 5200 caulk, using a very narrow tip to ensure complete filling of the gap.  Smoothing with a wet finger to make it pretty.

If you are really racing crazy...  you could use this as an opportunity to re-fare the keel....  or wait until some of the material either softens or falls off to deal with it.

The surveyor wasn't concerned (and didnt have any explanation), as the keel seemed to be solid... and honestly I wasnt too concerned because the bilge has always been pretty dry, it's way low on the keel, it's underwater and with a good coat of paint out-of-sigh-out-mind. But, I've always wondered what the heck is going on here. More than a few boatyard conversations havent turned up much, so I thought I'd kick it out to the group...  See the attached images... Any ides?
