OK - I am pulling the door panels off next weekend to re-wire my windows and
side mirrors, and while at it I plan to install some sound deadening
materials.  I have spent hours poring over the archives on the subject, as
well as poring over the manufacturers' web sites, and I am TOTALLY confused.
Why do these companies have to make a dozen products each that all sound
like they do the same thing?  Grrr....

Can anyone provide definitive advice on which of these products to use in
the door panels, and why:

  B-Quiet Extreme
  B-Quiet Lite
  Brown Bread
  Dynamat
  B-Quiet Vcomp
  B-Quiet Lcomp

For the life of me, I cannot make sense of it all - they all sound the same
(no pun intended).   Also, is there one of the products that will replace
the "mat" that is installed under the carpeting in a GL Vanagon?  (It looks
to be made of a mixture of felt and cork).

Thanks in advance,

Brent Christensen
