I just bought a 1952 Lone Star Coronado off of craigslist for $200.00. It came with everything you can imagine including leaking seams. I pulled all the seats out and all the other crap and cleaned the boat thoroughly and then tested it's floatation capability. I filled the boat up with about 3" of water and the water started seeping out from the inside joint (along the bottom of the boat) and on out to the outside of the hull and onto the ground. I noticed there is like a strip of rubber (or something) sandwiched between those two joints (on the outside of the hull) and then riveted together. How in the world do you fix this leak along the seam of the boat? I'd really like to use this thing this year if possible.
