How bad is the damage?
I thought all good body shops were stud welding to pull dents these days???
First I would find a body shop that does stud welding, then second once they get it pulled out to 80%+ is when they do a skim coat of body filler just to make sure everything is smooth the way it should be.
Again, he is right about a stud welder. See pic below. That is the way to go. If that doesn't work they can weld tabs on and pull it out. Or, try get it from the inside with pry bars/jacks...whatever works.
That panel doesn't need to be replaced. I wouldn't do it and I am pretty fussy. Nothing wrong with filler if it is done right. It has come along way since the days of "slap a coat of bondo on 'er". That repair should last the life of the car if it is done properly. When I worked in the industry we would aim for 1/8" thick filler max.
If they want to replace it I personally would refrain. I never liked the idea of breaking factory seals and welds. Also, if it is repaired make sure the inside of the panel is undercoated after.
