    The plywood needs to be sealed with something, and epoxy works great.

    But even the best epoxies don't have great UV resistance. If just being compared to other epoxies, some do OK. But being compared to coatings that do have good UV resistance, even the best epoxies turn yellow and get chalky quickly in comparison.

    Now if there's some super epoxy chemistry that has great UV properties that I'm not aware of, it would be a huge change for the entire industry.

    The guy I bought the boat off had let it go. 1/3 of the floor still has some very old vinyl mat on it. The other 2/3rds of which I removed 1/2 of was down to the fibreglass and cheap paint. So the floor is going to get covered with something and some of these floor coatings are easy enough to roll on assuming they will stand up, so I’m just thinking ahead and looking for ideas for easy floor finishing that will stand up. Was even thinking of painting the boat from the gunnel up with that stuff. Carpet is always a good option for the floor. . This floor is wide open to lay it on.
    The resin was on sale 3 gallons for $170 so I figured it wouldn’t hurt to switch to epoxy for the stringer fillets and encapsulating. Should have enough to finish everything.

    Seal the ply then lay seadeck on it. Looks great ..soft to walk on and cleans easier than carpet.

    Got my two outside stringers glassed in and encapsulated doing the middle stringer today then most of floor can go back on. Leave back ft open til install new drain plug and a couple of bilge pumps.

    Been busy with other stuff but have been chipping away at the boat. Stringers and transom/motorwell supports all encapsulated. Floor peanut buttered down each side and screwed down with decking screws. Leaning towards some kind of epoxy paint with some anti slip grit in it to paint tbe entire floor. That should eliminate having to glass the new floor, but what say you? Will cut back the motorwell supports back towards the back of the boat after I hang the motor so I know exactly how small I can make the motorwell. I don't want it any bigger than neccessary. I still need a couple wraps of cloth and glass from under the old keyhole starting four inches under the bottom of the boat up the transom and down the inside 6 inches and then add 3" to each end on the second layer and after some sanding the back of transom should be ready to gelcoat.
    Then hang ghe motor and get the motorwell built glassed up and installed.

    Epoxy paints are not equivalent to actual epoxy. It won't do nearly as good of a job at protecting the wood.

    Thanks Ondarvr. I wasn’t to sure guess I will throw a layer of 1708 and glass on it first.
