EPDM maybe?
Was thinking EPDM or TPO as an alternative. Certainly they seem easier to handle/bond to the marine ply than aluminum. Probably cost the same or less.
Or the other alternative is to coat the marine ply in fiberglass...messy though.
you could also use Cold cure or WEST epoxy,
it waterproofs the wood completely,
and is aplied with a putty knife or squugee as its very thick kinda like honey,
however it still needs to be painted over to protect from suns UV light.with paint or UV resistant Varnish.
downside is,its very messy very expensive job,And I would not recomend it unless its for small job such as kayak or a canoe where you need to see the beauty of the wood grain
to insulate your interior easiest would be to use the Blue or Purple Expanding foam thats sprayed on,dont know the Trade name,only seen it on Holmes house improvement show..its vater proof and vapor proof,just need to be covered with plywood
or paneling for protection as it soft and most likely flamable.
