It will have to be metal worked to remove any sharp dents. I hammer & dolly them up a bit then use an OA torch to shrink the spots followed by more of the same to get it as straight as possible. Shallow stuff can be worked with a shrinking disk after a bit of hammer work brings the low spots back up.

A lot depends on the thickness of the metal when using paintless methods. Modern cars have thinner and sometimes harder metal than older cars. Most skin damage stretches the metal and depending on how much it is stretched will make the difference on how effective the paintless methods will be.

If you are seeing 100 hammer created dents, ...then you likely have 100 individual stretched areas of metal. A Hammer & Dolly will not shrink the dents, -it only rearranges the form. Each dent itself must be shrank/shrunk within the confines of the dent itself.

Although I have not seen the trauma you are describing, -and not to contradict any previous advice given above however IMO you really need to use a shrinking disc in lieu of a torch simply because you really want to heat and shrink ONLY the area that has been stretched, ...and not the surrounding area that has the capture. Maybe another way to say this is, -every dent that is on the panel was caused by one blow. Each of those individual dents will need to be corrected one at a time since they were put into the metal one at a time.

Rather unusual is any pattern evident ? I have a 32 door skin with similar shot gun damage, just a guess

Rifle shots are great too
They usually stretch and flare the metal on the exit side
I find them easier to fix if you just get rid of flare and all
Patch a bigger hole but the stretch is gone

Well yeah... hard to shoot a rifle inside a vehicle but possible and loud. Never seen that
But most old cars that were sitting/abandoned were shot from the outside

I wished I had a nickel for every dime sized patch I've made. I have a very small Victor torch that I use to shrink small spots. It doesn't take as much heat as some folks might think and that's why a shrinking disc works pretty well. A lot of times I use compressed air to cool rather than a wet rag. A person should experiment a while when attempting to do anything with a torch on metal that they've never done before. Hammer and dolly work also stretches the metal so a person has to go easy on it but I know of no other way to move the metal unless a special weld stud puller is used but the weld studs have their own after affects to deal with as well.

I actually use a Miller head for their mig. Uses carbon electrode like a gouging rod for heating a spot the quench with air or wet rag.
Also use shrinking disc. A Stinger that welds studs comes with a head that will just heat a spot

That is a old very poor way of shrinking a panel. It also gave a foot for the Bondo. You are better off replacing those panels. JMHO

Not all panels are replaceable on model a”s
Can’t call up keystone and ask for a rear qtr for 30 roadster or rear section of a phaeton.
Some/many panels have to be fixed. True metal work separates craftsmen. IMHO

Shrinking with a torch should only be a last resort by someone with experience. You should not do that on a high crown area like the upper area on the door for 30-31.

Let restate the above, do NOT use a torch unless you know what you are doing. Even a small shrink does more distortion then you might expect.

A shrinking disk is the tool to use. It is slow and effective. Research it.

If you want to be able to do patches where the weld joint is not easy to see in bare metal you start with learning about stretching and shrinking metal. Once you understand how that works you will find you look at repairs in a different light. You also learn heat shrinks are very dangerous and must be carefully planned. Then only do one at a time and let the metal come back to the same temp before deciding on the next shrink.

That's my advice, take it as you will. I have learned the hard way.

A bit off topic but my Father spoke of a regular customer who while on a hunting trip discharged his shot gun in his 36 Chevy distorting the roof panel, & being a lead/metal man successfully shrank the badly damaged area, however getting a good paint bond was a problem over time I presume some tension still remained to cause the finish to crack.

You mentioned “lead”
If he actually leaded the fix there could be the paint bond problem.
Neutralizing, acids and waxy bleed~thru were always problems
