I already finished my Tuffcoat and used Polyurethane between the deck sheet and transom on top, entire floor, gunnels and I ran silicone between the gunnel cap and sides on the outside. If you look closely in the picture you can see it. I learned a trick to touching up areas you want more of the tuffcoat base and less texture. After your last coat is dry to the touch, take the leftover Tuffcoat in the can and don't mix it. Let the rubber crumbs settle and just use a disposeable brush to brush on a little extra polyurethane on areas you want to cover more and fill in. Worked like a charm.
