I can now tell you the "Tite Seal" I bought does not work.  It is
sold as window flashing.  I put it inside the passenger door and
thumped on the outside of the door all over the place and didn't
notice much difference from the driver's door with nothing in
it.  Not much difference between the sound of closing the two doors
either.  Then I got some Peel and Seal today and put that in the
driver's door.  There is a definite dampening of the sound and
lowering of the frequency of what I hear when thumping on that door,
or closing the door.  I measured with my digital caliper (whose
battery was near death) and got .73mm thickness for the Tite Seal and
1.3mm for the Peel and Seal.  There you go.  Maybe Tomorrow I'll get
the speakers back in the door panels and the door panels back on and
really test it out.
