A single layer ANYWHERE on the door panel will fit onto your door skin. The clips that hold the panel on.. create a good.. 1/4space inside the door panel and metal door skin.

I used 2 layers..of extreme on my entire door panel. Make sure to get rid of all the squeaks you hear from the leather and plastic rubbing... I had a few And I placed friction tape between the 2 rubbing areas. I removed my black strip that runs along the top of the door panel and placed a thin dab of silicone on the back of the strip before I placed it back on... it was squeaking when I placed my elbow on it as you drive before :rolleyes"

The arm rests.. tend to squeak somewhat.. I toook out the screws of the arm rest and pulled it out.. dabbed a thin layer of silicone on the areas where the arm rest attach and reattached the arm rest... I removed the styrofoam block that's there.. eventually taht rubs and squeaks against the plastic..

Just shake the panel againt the carpet of your house and it should sound solid... after you silicone, friction tape and sound deaden it... because no ones wants to take off their panels OVER and over again for recurring squeaks ... I've been there.. it's a bltch..

And by the way... take out the carpet padding... it doesnt do crap against vibration.. I found out after all.. and eventually moisture and humidity.. the spray adhesive doesnt hold all that well and the stupid carpet paddings plop right off... in its place use any sound deadener and layer about 2 layers... muuuuuuuuuuuuuch more effective.

Friction tape wrap all wires going to the door panel.. as they will vibrate and rattle eventually... *phew*

That looks like the backside of your door panel?

You should apply the material to the metal frame portions of the door, bot the plastic on the back of the panel.

Uh no... he SHOULD apply it to any object that would resonate to it's own Fs. Even the plastic panel will humm and bltch when given a specific frequency that vibrates it to holy-hell...

In addition honda door panels.. arent of the best construction and tend to squeak, moan and rattle as they get older.. so dampening the plastic is a must.. when you add to that external acoustical vibrations of insane midbass

and is it true, by just adding a small piece of dampening to a slightly larger panel, it will keep most of that piece from vibration?
i know it wont sound proof as good as one sheet......
but i've heard that some put a small 1'x1' piece, for example, on one of their side trunk panels, and its virtually eliminates vibration

I've heard of that theory of "vibrational center".. where there is a central point.. similar to droping a rock in a pond and the central disturbance produces outward waves which inturn disturb surrounding areas..

but good luck finding that vibrational point... but I suspect there are many little vibrational points that sum up to a whole.. so it's just better to dampen the whole dam thing.

I don't know how much I agree with this.

Honda Engineers use the door cavity as the acoustical chamber for the door speakers. By applying the the damping material to the outside layer of the metal of the door, inbetween the doorpanel and window mechanism, you will eliminate most of the resonance from the door. Another good idea would be to put the acoustic pad behind your door's drivers. Plastic will always rattle in a car, no matter if you have it covered or not.

The plastic cover is not what rattles or squeeks. Its the door hinge or the fastners for the door panel. Also, adding added wieght to a fastned article can only weaken the fastner and cause more squeek and rattle.

You can try each method. You can read dynamats FAQ on proper procedures for doing this. It will help your Accord sound like a Lexus with no music at all. Eliminate exterior road noise and drop your floor nosie some.

LOL Vtec has a few valid points while other are ummm... but let's end it here.. I think Lou gets the message to try to diminish what he can in terms of vibrational induced rattles, squeaks, etc...

But I'm all for a healthy contradictory conversation where both sides convey their own view points and in the end L_fty wins the debate and buries Vtec into the ground with a Adire Tempest sub as his grave stone. juuuuuuuuuuust kidding bro

I am not trying to start any disputes, I am just stating from my experiences. Just trying to make the V6P world a better place.

I wouldnt.. it would inhibit movement of the bar.. use some weather strip foam.. with the one side adhesive and place it behind the bar.. so the foam will allow movement....

well, i planned on wrapping it, leaving the parts that need clearance to pass thru something free of any tape.
we'll see
