Like Sailormon6 says, the keel construction is (from the bottom up) lead keel, 5200 sealant/adhesive, fiberglass, plywood and then fiberglass that is visible from the bilge. I have the aforementioned sheet from Catalina that shows the keel stub construction. Let me know if you would like me to email it to you.
From what you are describing, it sounds like the black layer is actually part of the hull layup in places (since you had to grind through it to get through to the bilge), and if that is the case, I agree it sounds like something used in a previous repair.
