Hi, Mike -
I wouldn't swear that the stuff I tried to use was "Dynamat", but my
recollection is that that was the brand name of what I bought at the local
auto parts store. It has been a few years, and my memory certainly isn't what
it used to be, so I could be mistaken.
Another thing I remember is that it was quite expensive for a 3' x 4' piece.
Is there a difference in material and construction between "Dynamat" and
"Dynamat Extreme"?

Steve,
What you used couldn't have been Dynamat. They have no felt.
It's rubber and foil.

Dynamat Xtreme is a patented, lightweight elastomeric butyl and aluminum
constrained-layer vibrational damper. Dynamat Xtreme conforms and fuses easily
to sheet metal and other hard substrates. Material performance is optimized
for temperature ranges between 140F and 1400F (-100C to +600C). Material can
withstand temperature extremes between -650F and +3000F (-540C to +1490C) and
is highly resistant to aging.
Appearance:
Black butyl based core with 4 mil aluminum constrain layer, craft paper
release liner
