I have a 1981 Hunter 31. In the summer of 2019 we had the steel keel sanded and three layers of epoxy applied. The bottom was then painted. Everything looked good. Yesterday we pulled her out of the water to fix a stuck seacock and I found a weeping spot on the keel. There is one on each side, but the port side is much more pronounced. Anyone know what this is before I dive into another expensive repair?
