I just got through restoring a 14'. Check to make sure the hulls have intergrity at all points. Seal everything and then use a blower of some type in the drain plug hole to look for leaks with soap bubbles. I used a test from beachcats (www.thebeachcats.com) to determine how much flex I had in the frame system. With the new tramp and the additional stiffening to the hulls, I decided not to epoxy.
