but expanding foam will not stop the resonance on the panels. it works well to fill voids and gaps in the car, but will do little for actual panel resonance, which is why you need a heavier material stuck to the panel which stops that.

My kids go to Bass competitions.
They told me about expanding foam.
It is fairly cheap, seems some guys use it.
Tar mixed with sand works real good too, just takes forever to cure, adds weight.
I would think the expanding foam will be the lightest.
