With apologies to the Bard of Avon, to seal or not to seal, that is the question. I'm laminating a 93 x 29-inch transom from three thickness of half-inch ply, using thickened epoxy. Is it better: (1) To first seal the surfaces to be glued with unthickened epoxy and let it cure befor gluing and clamping the plywood, or (2) to apply a saturation coat of unthickened epoxy to the surfaces and glue with thickened epoxy before the saturation coat begins to cure (possibly encouraging a mechanical bond with all the fibers of the untreated wood), or (3) just use the thickened epoxy without worrying about sesaling or saturation? I'd appreciate any advice from the resident wizards, and thanks!
