A question for those of you more adept at chemistry/physics than I: How
fast does the aluminum skin of the standard single engine GA aircraft take
to cool to surrounding air temperatures? For example, how long would it
take for the skin to cool from a heated hangar at 65 degrees F to outside
air at 20 degrees F?

Nor more than a couple of minutes. Aluminum is an excellent conductor
of heat.


How well aluminum conducts heat has nothing to do with it. It is all
matter of thermal mass and surface area to mass ratio. The good heat
conductivity or aluminum means that once the outside of the plane has
cooled off, the inside will cool off fast too.
