ome tweaks here and there to smoothen the jointing edges between the hull and deck, putty – seal the bulkheads to the deck, then some slight overall fairing and sanding before putting on the final layer of fiberglass to the bottom part. The glass will marginally wrap over the deck (about 1 inch of overlapping) to strengthen and completely seal the joint. Deck would have no fiberglass on the external side, and would only be clear – coated with thinned epoxy and polyurethane (PU) paint.

4th image below: the deck thoroughly sanded with 100 grit paper, it looks quite fine now! In my previous boats, I was usually over sanding, with multiple grit – levels applied, and lots of efforts too. But now, I’d realized that I actually don’t need a furniture – grade finish (and I couldn’t do it as nice as a professional woodworker nevertheless). After all, a boat is a functional (not a show – case) object with lots of hard and harsh uses. A too perfect finish wouldn’t be of any practical good!

5th image: the deck has been stained with thinned epoxy mixed with color pigment (yellowish wooden color). The white duct tapes mark the area of wrapping when glassing the bottom. 6th, 7th images: glassing the hull exterior and wrap the fiberglass an inch over the deck. I used exactly 300 gram of epoxy mixed with dark brown wooden color pigment. A lesson learnt from the previous boat: use lighter colors for the wood to appear natural, too strong, deep colors look very… ‘artificial’.

About polyurethane (PU) paint: it’s a broad category of paint with different sub – types and applications, but in Vietnam, the term is narrowly and misleadingly meant to be one used for (semi – clear color) wood – surface finish only, as people is only familiar with that widespread use.

So if you want to see other types of the paint, say: Polyurethane, don’t say PU 😬! As the vendors will assume you know nothing about it, and by telling the chemical formula, you would be given more choices, don’t say PU, or you would be wrongly given the interior / inferior furniture finish!
