I don't know if others would approve, but I just used some Marine-Tex putty down there. Took a skinny putty knife to smooth it down. It's not the prettiest repair, but I was doing little spot repairs (chips in the hull, a crack near the bottom of the trunk). Since you're on the curve, you might want to try some cheap wooden kabob spears.
I made my solution on the goopier side, think ketchup, and it hardened up just fine. It's thin enough to spread well, but thick enough not to run.
