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
Thickness:
