The alloy may be the same. At the time your car was built, weren't the
english still hammering cars out of bits of aluminium from the wings of
downed aircraft? As you strip your car, watch for "no step" stencils.
Of course, there's always the possibility of a chemical reaction, in
which the hot NaHCO3 solution reacts with the aluminum, turning Roland's
Snake into a sort of Roland's Rolaid.
At least the Rolaid transformation should eliminate the snake's gas
problems.
