This weekend I fiberglassed the cockpit of the hull interior and encapsulated the entire hull interior in epoxy. 2 coats are recommended I did 3 coats in the cockpit and two on the rest. You can see the results up close in the photo below, the fiberglass weave has almost completely disappeared.
I also wet out the fiberglass tape in the deck seams and encapsulated the underside of the deck with 2 coats of epoxy, which really makes the Sapele wood grain pop. I didnt sand the glass tape seams on the underside of the deck much at all. I figured no one would see the underside of the deck so I only sanded enough that it wouldnt be rough on the paddlers knees if they rub on the underside. I've noticed my fillets are a little larger than others I have seen so my WoodDuck is not likely to be the lightest one ever built but I bet is rugged and lasts for a long time.
I should be just about ready to attach the deck to the hull sometime this week. Man, my shop is a mess, someone should clean it up before I trip on something......again.
