If you plan to completely coat the inside of your boat with epoxy, it will obviously be necessary to apply it to the bottom of the ribs and the bottom of the keel before you attach the plywood.
Turn the boat upside down and coat the bottom of the ribs and the bottom of the
keel with epoxy. Measure the first piece of plywood that you have cut for the
bottom, and coat it well
with epoxy in the areas that will be attached to the keel and ribs. When you
have finished
attaching all the plywood to the bottom, you
can coat the entire inside, but make sure that you first epoxy under the ribs
and keel.
