Sanding the fiberglass on the interior was much more difficult than sanding the exterior. Because of the tumblehome of the canoe, the curve was hard to sand with the orbital sander. Also, while applying the epoxy to the inside, the epoxy wanted to run because gravity was forcing down. Near the bow and stern stem piece the epoxy began to pool, so I used a sander extension on the dremmel to make it smooth. Sadly, while applying filler coats of epoxy, some epoxy got on the outside of the canoe which had to be sanded off. Sanding with 80, 120, and 220 grit, the interior of the canoe is finished except for a last sanding and then varnishing. Some canoe manufactures even used to sell canoes this way (without trim and detailed interior). The next step was to work on the two decks at the bow and stern.
