Annealing or normalizing after shrinking helps to return the steel to its
original condition, though he didn't mention that. Remember too that
stamped panels are already work-hardened a bit unless they were normalized
after stamping, which AFAIK is not and was not commonly done. Some
additional hardness can be a good thing - adding strength and resistance to
dings, etc., though as you point out, too much can be cause problems.
