Foam in frame?

[soundcontrol]

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.
