www.audiotechnix.com Is the best cost effective sound dampening material. It doesn't prevent noise but stops panel resonation. I've used this product and will vouch that its as good if not better than second skin. But they do not offer anything other than butyl based dampeners, that's why I suggested second skin because u can get all you need in one place. Also another good place to check is sound deadner showdown. I don't know the exact site. |

In what way is that better or more cost effective than what I used? |

FYI... When applying sound deadening material or expansion foam, keep in mind all forms of drainage, and moisture forming areas. Especially in cold places, there is opportunity for condensation to form on the backside of your interior panels as well as quiet areas. Quiet areas are those with limited or no airflow. If you noticed, those who have taken there interiors apart have found the bare metal supports contain surface corrosion. This comes from such moisture. I have worked in the aviation industry for over 23 years and am well versed in combating/ preventing ocrosion. PM me if you have questions. |

Still can't spell corrosion though. Dommit mon, check one for corrosion! |

In my experience, there's a difference between sound deadening and vibration dampening. Bass heads use Dynomat and other vibration dampening materials to control panel vibrations. These products vary in their material, many are asphalt, but they all adhere to the metal and add weight to control vibrations. I did my entire truck some years ago with a cheap Dynomat knockoff and noticed no reduction in road noise, but a lot of added weight. Probably over 150 pounds. Sound deadeners are usually some kind of closed cell foam, neoprene is an example. Most but not all adhere to the metal. They are usually lighter than vibration dampeners. The cheapest place I've found is FoamForYou I'll probably put some in my Geo when I'm done painting it. Of course, you could use both together and I know many people do. But then you have to be careful about not adding too much material under the carpet and making reinstallation difficult. Brian |

Lizard skin is a sound deadner. it can also be applied on the exterior as primer as well. It will make the car even quiter and make it lot lighter than other soundproofing |

Is nobody going to agree with snowfish? I love the cheap answers, and if carpet padding does the trick then it works for me. When adding any of these, is it a good idea to pull off the old padding that is attached to the carpet? |

On the floors. I removed all the old padding. Used a layer of peel and seal, layer of carpet pad and another layer of peel and seal. In the quarter panels and rear, including the trunk (Vert), I used peel and seal, spray foam, aluminum flashing cut to fit and covered with peel and seal and screwed over the body panel spaces. window peel and seal is thinner than roofing peel and seal. both bought froms Lowes, both almost comparable to other "specialty stuff" and cheaper. Lot of trouble--allow 3 times as much time and twice as much material and 3 times as much $$$ as you think.-----But VERY EFFECTIVE. Edited by Old Man, Jun 15 2012, 01:06 AM.

I did. Mine was just a fibbery, dirt encrusted mess. Plus, removing the old backing, makes it easier to scrub and dry the carpet.

I just ordered 25sqFT of 80mil sound deadener. I plan on putting the majority of it along the front lower firewall, the rear near the exhaust, and along the side-panels. I'll take pics and add to this thread my results! Kyle |

So I go to Lowe's just to see what they had in the sound dampening/insulation field, guy says nothing, but check O'Reilly's. Go to O'Reilly's, guy says Dynamat's expensive, but he was told "by a guy in the business" that there's something that's exactly the same thing that is used for window insulation for like 20 bucks a roll, that I should check Home Depot. Go to Home Depot. Nobody's heard of Dynamat, nor anything that I've described. Does this mystery product sound familiar to anybody? |

![]() This is "peel and seal" for roofing. ![]() This is "peel and seal" for around new construction windows. both of these are found at Lowes. Check the roofing and windows&doors section. for windows is 1/2 as thick and is good for curved sections. for roofing is twice as thick and is good for the floor etc. SEE POST #24 above.......

Cool, I thought "peel and seal" was just a description not a brand. I love that this is for houses yet most every review on Lowes.com is talking about vehicle use. |

I am wondering if anyone has used cellulose insulation? I have had the idea for a while about making fitted "bags" out of some inexpensive cloth, and fitting them to the inside of the doors, maybe making them stick with some headliner glue to the metal. The cellulose insulation has good sound deadening properties, and is very light. I have a decible meter, and if I get around to trying it, I will do some before and after tests. |
