The asphalt based material you refer to is available from Victoria British
(and I suspect from MM, too) custom cut for MGs (this looks like the same
stuff they came from the factory with that is painted body color and fits
between the ribs in the floor pan). It's not necessarily cheap, but is
available.

I have been seeking a bulk source--i.e., by-the-yard--for an
asphalt-based
underlayment that I have used in my Mustang with great
success for heat,
noise and vibration. I can get the stuff custom cut for
Mustangs, but cannot
find anyone else who has ever heard of this stuff, and the
Mustang folks
won't sell it bulk. I had to take a pre-cut Mustang package
and recut it,
badly, for my roadster.
I've always wondered about the wisdom of using any felt or
fabric-based
material for sound/heat proofing in an environment in which
water is often
present. The felt traps and holds the moisture, giving the
tin worm too much
help. The asphalt-based material cannot absorb the water,
so it is free to
evaporate faster.
Also, what is it with this aluminum skin that is put on some
sorts of felt as
a heat barrier? Anyone ever cook with an aluminum pan?
Hello? Aluminum is
one of the greatest conductors of heat you can find. Great
at reflecting
radiant heat, the worst at defeating heat when in direct
contact.
So how about this asphalt stuff, whatever it is called.
Any help?
