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.
