Craig,

I agree entirely. But I am not sure just how much of panel you really
need to cover to stop vibes.

I covered all of panel, 3 layers :)

be careful in doors not to have window mechanism impeded. Its tricky
to get the stuff up in there.

Oh the stuff makes the panels dead as a door nail. Door closing,
thumping etc. But I have to say, next time I will use less peel and
stick, and add a layer of closed cell foam.

oh, btw I did front well, but not up under dash and front panel. in
back I did floor, sides, and up that angled face under rear seat. i
did not do over engine bay, I thought I could find a removable pad to
go under rear foam.

My experimentation involved just the front doors, so far.
I used one roll for just the front doors. The key is not to use it to
try to
keep sound out, but to cut down on vibrations. You'll see VW even did
this
in some strategic areas with a single thing coating of a similar
material,
just a strip adhered to a large metal panel. It doesn't take much to cut
down on vibrations, but additional layers can help cut down on noise
too. So
just make sure it's contacting all the nooks and crannies and directly
touching the largest metal surfaces.
I found it sticks just fine, but a hair dryer and Edge Banding Roller
from
home depot make installation all that much better. Heat it a bit,
roll it on
with some pressure, roll into all the little details..... and it's
there for
life.

The "seat of the pants" difference is very noticeable not just in
closing
the doors, but in assuming the cliche VW Bus driving position (at
least in
warm months) of placing one's left hand out the window along the side
of the
door. While rhythmically "thumping" the door to the sound of CCR, you'll
notice a more pure and deeper bass tone, far less "tingey".
