This is far beyond my current skills, but I've also read of heating the area
with an OA torch and then quenching it with a wet rag. This will supposedly
shrink the metal, and solve "oil canning" where you have big ripples that
move around when you try to work them.
There are also "shrinking hammers", but it seems most people say they don't
work very well.
