Sound proofing, What Sound deadener coating?
HI just installed my system, and like many of us the aftermarket exhaust really clashes with it...
I just bought some Second Skin damplifier pro, but would like to coat it with some latex based sound absorbing paint as well.
What is the most effective product out there for in and out quietcar, lizardskin??looking for something that won't make my car smell like plastic/rubber factory.. like the old dynamat.
Also I've read some people coating on top of the padded mats, wouldn't it be be more effective coating the metal, and then putting the mats on top of that?
Thanks in advance for any suggestions!

I knew a Seas Lotus worker that used to (or still has?) a S2k and he said he couldn't lower an all stock S2k interior to below 60dB noise level... And he was one of the USAC finalists...
If you really want to do it, I'd recommand using HushMat mat and foam. They are the OE supplier for BMW and Land Rover etc.
* The stick on closed cell foams are lighter than deadening paint, and they focus on mid to high frequency noises while being highly compressable. The mats takes care of low frequency noises.

Where you put the dampening material is more important that the material itself from what I learned. Generally a good thick layer of butyl-based material (e.g. Dynamat Extreme) to the metal and a nice thick layer of foam or carpeting should give you great results. Becareful what type of foam/carpeting you choose though e.g. avoid open cell foams or carpeting where it can get wet. I'd suggest focusing on noise reduction in the following general order:
- Door Outer skin
- Get a Hard Top
- Rear Tray
- Trunk
- Door Inner skin
- Drive/Passenger footwell next to front wheel
- Air vents to trunk
- Floor
- Hood liner
- Motorcyclist Earplugs

hmm... the places that I would start working on are:
1. Door Outer Skin: 2 layers of mat
2. Door Inner Sking: 1 layer of mat
3. Door Panel: 1 layer of foam
4. Rear Wheel Well: 1 layer of mat, 1 layer of paint, and 1 layer of foam
I'll then start working on other areas that are necessary.
