Foam in frame?

Have a friend thats repairing rust on a 70 Charger, he found that the A-pillar and some other places on the car was full of foam. I never seen that before, was that something the factory did in 1970? I know some other European cars had it, but Mopar?

I see foam between the inner hood brace and the hood skin on my 73 challenger. Don't look like seam sealer. It is painted body color.

Yes, I have that also on my hoods, some kind of sealer. Never seen it inside frames or pillars though.

I've torn apart a lot of old mopars. Never found foam in the A pillers, rockers, kick panels, frame rails, etc. However, I could imagine someone buying a can of Right Stuff and injecting it into places hoping to insulate, quiet, firm up an old car.
