A reasonable guess can be made - a decade or more. The lid and bottom
of a Pepsi can are about 0.010" (10 mils thick), but the side wall is
only 4 mils. Deep seawater corrosion rates for the aluminum alloys
used in cans are roughly 1 to 3 mils per year. So, you could expect
five years or more if both sides were bare and ten years or more if
one side was bare. Actually both sides are coated,so the coating also
has to fail.
