How to shrink sheet metal with a torch.

Heat to blue only and shrink that much. Although dent shrinking can be achieved with a shrinking disc or a spitzenagle stud nailer gun in order to shrink a bead you will need a heat source that produces a flame. I use a jack stand with a trim panel pry tool clamped to it to hold my torch. If you ve done it right this action will cause the metal to pucker on the edge and give you a little ripple or ridge.

Do not over heat the steel. Start by placing the sheet metal over the bowl so it covers the bowl and lays as flat as you can hold it. Why not just heat it and gently hammer the swell down. Device to hold your torch safely while you re doing the hammering operation.

The bulge can then be tapped down flat with a hammer and dolly to thicken the metal in that spot. A common recommended fix is to use oxy acetylene heat to create a localized hot spot that bulges the metal above the mean surface of the panel. Then take your teardrop mallet and make one hard blow on the metal driving down and towards the outside of the bowl. This takes away some of the stretch.

Get used to this idea and your abilities will grow.
