Re: Which emergency use fibreglass matting should I have?
Good ideas. I was thinking about how to seal the repair of a plywood hatch cover. Still consider using toilet bowl wax to stuff in the "lip" of the gap between plywood and deck. Think: deck, rubber matting, plywood with the wax to fill any cracks. Or use pieces of cloth to fill any gaps. Then I thought (the reason for this post) ... I wonder if you could use expanding foam (like from an aroseol can you buy at a hardware store). Would it become waterproof? Would it set in a moist environment? It would be interesting to experiment with it, to see if it works.
