[Basketcase]

That sounds like good advice. I had planned to grind the whole keel anyway and lay some glass on it so perhaps I should do it before I attack the inside. I did already grind the inside before I laid that piece of glass and did not notice anything major but perhaps the underside will tell more. I have to grind off that old repair anyway. I will do so and report back with pictures. Any damage to the keel will get repaired with epoxy for a worry free repair. Im using vinyl ester everywhere else but I think the keel is worthy of the strongest materials possible. Even though this boat will never see seas over a foot while in my care. Lol.
