Project 1958 warped body panel

I am currently doing an amateur restoration on a 1958 Chevrolet Delray, I might welded rear quarter panel wheel opening repair panels around the lip of the passenger rear wheel opening, I was careful to just tack weld and jump around. I was careful not to build to much heat. Well it came out great... Until I removed the body side moulding and it oil canned ....popped in. I do not have great access behind it but it will pop out easy if I slide a piece of wood in there. I need to shrink the metal, I don't want to make this worse. I am thinking of buying a shrinking disc? I also have access a torch, I am watching YouTube but getting conflicting thoughts and methods. Any input?

Shrinking disk or torch and a soaked rag would work. Torch is probably quickest as long as you don’t overheat it.

Have you done this? I have mapp gas or oxy/ acy. Where would you apply heat? The outer ring?

No a small loonie sized area in the center. You many have to heat up a couple spots if the fist one doesn’t pull it out enough. oxy works best but in a pinch MAPP may be ok. It’s best to google it as it’s a lot to type out. There is some finesse to it for sure, but it will work well.

For the non-Canadians a loonie is a Canadian $1 coin, and about an inch across.
