Buying a new Chrysler van, and the salesman was tauting a new "alloy"
that he said Daimler developed. He called it an alloy, but the
description seems to indicate a laminate, plastic on steel. I am
assuming it is a single layer of each. He said it provides both
corrosion resistance and sound deadening.

I have never heard of such a material, though I know that they have
been putting a plastic, adhesive backed film on lower external panels
for some time. That is not new. Is there something really new now?

If it's a laminate, plastic/steel laminates of various kinds have been used
as sound-deadening materials for decades. The first time I encountered it
was when I had to write an article about a (then) new Swedish three-layer,
steel-and-viscoelastic plastic material called "Antifon." That was in 1978.
