Default planishing vs stretching

Hi Group,

A basic question of how do you know when your planishing a sheet of steel vs stretching the metal. I'm assuming that some of both is happening using hand held hammers.
I'm not seeing the smoothing of the metal that I'm after (planishing) and I'm hoping it isn't getting much larger. This is a patch panel piece for a front fender that has a low crown bend to it.
I've also read about planishing welds, is this to smooth them out after grinding, filing, sanding to a OK finish then final smoothing with the hammer and dolly to planish the weld.

So the real question, how best to explain planishing metal for a beginner?
