    I have re laminated teak plywood on the cabin sides in our W42 salon area and before installing portholes am going to seal the wood work. Also, going to seal the porthole cut out edges as a precaution to help against water intrusion. ( if it ever leaked ) The cabin sides were badly damaged from leaks around the large ports as well as smaller ports. 

    What is everyone using ? A sealer then varnishing or urethane? It looks like the cabin had different products applied in areas of the salon.

    Thanks,

    George

    I took ply wood and sealed with epoxy, then epoxy glued to trunk.  Then glued veneers to the ply.  Then cut out the portholes then epoxy sealed the cutout so there was no void.  In that way if water intrusion occurred it wouldn't soak the wood.  Then lastly I used outdoor clear uv satin varathane spar varnish on the veneers.

    The last pic in my member photo album shows the varathane and portholes.  Not a quality photo and for that I apologize.  I haven't taken good photos yet just work in progress stuff but you'll get the idea.

    We did pretty much the same procedure laminating the plywood and veneer. Still have to do the final trim around the porthole cutouts and am planning to seal the edges with epoxy. What did you use to set the portholes? Once done with the ports in the main salon, we will be removing the interior to replace the water and fuel tanks.

    Butyl but if I do it again maybe something else as butyl is so soft it oozes out.  I literally don't tighten the bolts.  I wait for the butyl to ooze and as the bolts loosen I take up the slack.  The surface tension of the butyl is adequate the bolts are just there to keep them from "working."
