I have a 1977 no-frills work boat, similar to a lobster boat. Glass over plywood. I want to extend the cabin roof ONLY (no sides) 6 feet back. A friend says canvas from an old tent I have could be ''glued'' to the new plywood roof with a generous application of exterior epoxy paint then saturated with a few coats, the last one with sand in it like the rest of the boat for safety's sake. I don't plan to stand up on it except to maintain the inflatable tied up there.
Has anyone tried this ?
Best wishes of health to all from up North.
