I have a real old De-Haviland tinny which has a bung in the bottom ..last trip the bung came free and it was amazing how much water comes through a 1 inch hole in the bottom....once we realized where the water was coming from it was easy enough to stop and we made it home OK...
Upon inspection the bung-hole has corroded out and the bung was simply sitting in place held by a generous helping of black sealant...I only use the boat for the creeks and am wondering what product I can use to hold the bung back in place that might seal it up and last a while...???
