Answer:
i haven't done it yet but I'm going to etch the surface with coarse sandpaper and then apply contact glue to both sides making sure the two sides have vulcanized(alcohol desipates away) then be sure that the two surfaces are where they will forever reside and bond them together. then use a small hand-held roller for removing the air bubbles. sheet should be over the actual size needed and then final trimming is to be done with a router bit that has a cased bearing which will not fray or splinter your edge. making a perfect edge for your choice of facia(front finished trim). which covers your substraight(plywood or particleboard)
