The submerged time was 24 hours and considerably longer than the 1 hour that
I indicated.

IHMO however, a Water Proof glued joint being submerged for 1 day during a 4
day test is not beyond the manufacturers stated limitations of continuiously
being submerged or use below a water line like a glue aplication on a boat
bottom.

I guess we should ask Franklin what their definition of Water Proof is.
