Just reinstalled the four windows that were leaking, as well as some deck hardware. Thanks to the gaskets from Bomon and the butyl tape from Maine Sail, the windows are watertight, and we are nearly leak free. Just have a couple of stanchions and dorade boxes to get to when we repaint the deck. Thanks for the help - I think our results have made believers out of several people on our dock.
