Mods, why is this thread in the shifting gears section ?

Yaar LBM, I had a talk with somebody at the Dyanamat. Those guys said that the shiny side (the alminium side) should come on the inside. While in your set up, I am seeing it just opposite.

Also they said that the damping material is to be pasted/glued on to the metal surfae, i.e. the door's outer panel. Here again, i am seeing that you have pasted most of the stuff on the inner board like stuff of the door.

I am not sure about your material, I enquired about Dynamat Xtreme. I have also bought one door kit (20ft) of Xtreme in mere 2000INR (after conversion) from the US, for my alto. I guess enough to cover the front two doors.

Any comments ?

Ok while having discussion with the Dynamat guys, they told me that the material actually damps the vibration energy and thus the deadening effect. The sound waves, the vibrational rattles are absorbed in the material and that is precisely how the dampening works.

The steel parts, being highly rigid, vibrate more compared to the inner plastic/board layer. The inner layer, being of board itself has some dampening effect so you dont really have to do it first.

The starting point has to be the inside of the door's outer metallic surface.

I am sure you are little wrong here.

I know I am new to this, but being a mechanical engineer and being a topper in my class in STRENGHT OF MATERIALS/Elasticity subjects, the explanation sound pretty logical and convincing.

I bet you are wrong here LBM.

Ok I just confirmed once again with them. You dont need to put the dampening material on the inner board. This is how they quoted " The best would be to add two layers of Dynamat Xtreme on each of the outer layer and the middle layer. If you only wish to use one, put it on the middle layer with the shining surface facing the inside of the car."

Here is the weblink that demonstrates how to DIY.

Correction in the previous post: I got 12sq feet, not 20 sq ft, as I mentioned in my previous post.

For 2000 bucks, I think I got it pretty cheaper. I just saw in the forums that people are selling trunk kit for as much as 18000INR. Here it is retailing for around 130$, close to 6K INR for 30sq ft.

the inner board needs stiffening. It flexes. This is rahter diffcult to do so adding the damping material, some claim, atleast pushes the flex resonance frequency to the lower midbass and to an area where the ear is not as sensitive.

To stiffen the inner board one would need to be a master in moulding and know exactly what each nook and crany in in the door panel can be covered in resin. resin (the prime glue in a mould) is difficult to contain and will flow into all the nooks and cranies it should not.

The process would be something like this
1. identify all the nooks and cranies that need to be protected from the resin.
2. test PVA on small part of teh door tosee if it attacks the panel material
3. fill these nooks and crannies with cloth soaked in PVA (if PVA is found to be suitable)
4. laying a thin layer (1-1.5mm) fiberglass rovings (not mat) down on all the area that needs to be stiffened.
5. carefully pour resin (mixed with hardener and accelerator) over roving. and let rovings soak in resin. over night or untill full dry and cured.

Now you know why dynamat is so much simpler. cut, peel, & stick; and if something goes wrong you can peel it off. FRP is permanant.

Hello all,
I have a zen and I'm planning to get some damping for it. Can anyone tell me from whom or from where I can get some Dynamat Xtreme in India?
If anyone has any Dynamat Xtreme for sale please feel free to P.M me.

Preeti Trading corporation, a mumbai based company is responsible for distributing Dynamat. But mate i would suggest go for Noise Kill, its VFM product. Dynamat is extremly highly priced for indian market.

I bought one door kit for close to 2000 INR from the US. Whats the legitimate price in India ?

And there was an ad in tlast months autocar with this link main called up the number,it's a goa based company the guy said 3,100 for a roll of 1x10 mtrs. Have any of you used this brand before ??

I think I missed a lot here...

1 x 10 meters that is approx 10.7 x 10 = 107 sq feet. That comes to aprox 29 rs/sq feet which is quite difficult to digest.

Firstly congrats on your academics.

Yaar no one is wrong or right here. Everyone has his or her own opioion. What you said is right. But if one has to put more damping or one has lots of damping with him what will he do. I had one 150 sq ft damping with me. So I thought to put a little here and there hence the door panel.

Rest about the door outer layer it has been damped. I think you know that the damping sheet is opaque which will not allow light to pass thus the inside layer is not visible. (just pulling your leg bro).

He he he !!! koi gal ni bai ji.
I just wonder sometimes how you manage to add so much of stuff.

I think sometimes ki meri kite lottery lagg jaye te main vi koi kaara karaan eho jeha.

Would you mind telling me how much have extra WORTH (not wurth :P...now me pulling ur leg) have you put in your car, on top of the base price ?
