Corkish deck treatment

I know there's someone out here that can figure the deck and cockpit areas
with a fancy formula. I remember using 120/130 sq feet for paint coverage.

So, how do our contendas compare in weight with 120 square feet of material? MD2K - SeaDeck. Is there logic in thinking the thick stuff will last longer than the thin?
Are there longevity differences between SeaDeak and MD2K? Is it a valid assumption that the denser material lasts longer?

The main reason for thinking about covering the whole deck in 1/4" cork is for its insulation value. If MD2K has the edge on longevity and turns into a nice beige when it on the deck awhile then thin sheets are the lightest way to go.

I don't know how the exposed edges hold up - maybe the deck could be painted in urethane, lpu, whatever, and the antiskid could be added on top in the form of cut pieces of cork sheet in whatever patterns that lifts your skirt. Maybe the best of both worlds.
