Default Sound deadener kit, insulation, undercoating?

Hey guys, since my ride is in the paint stages, and stripped of interior...here's my chance to make my oldie ride like a wannabe Bentley...lol.

I want to tone down the rattling.

What would be the way to go covering the floor panels before the carpet is installed?

Any recommendations?

I'm pretty ignorant when it comes to this...help a brother out...lol.

Thanks!


P.S. BTW, recommend something affordable...I'm already spending an arm and a leg with this paint thing...so be easy on me...lol.

I used lizardskin on my truck it sprays on works great for a 2 gallon bucket and sprayer was around 200 bucks.If you want cheaper then that most of the roll on or spray on truck bed liners sold at autozone can do the trick too.

You can buy the ceramic microspheres and mix in your own paint for a fraction of the cost. This winter I am thinking of removing the complete interior and adding this as well as sound deadner.

I read a lot of using latex pant but I really want an epoxy paint to add over primer. I just need to call one of the companies to find out a great paint. I guess the most flexible paint the better. Insulation factor with some reduction in sound.

I get my car back from the painter tomorrow, and I have a complete QuiteRide setup waiting to go in. Now I need to figure out how to insulate my convertible top!

There are two different issues that will need addressed, the vibration and the sound transmission.

For the vibration you could use a dynamat product on any area of the floor that sounds like a drum when you tap on it with a finger, it takes less that you may think. The tops of the seat risers for instance can act like a sound generator once they get going, so some peel-n-stick would help there, but the sides of the riser are short and stiff and do not "Hum" or "resonate" much at all, so I personally dont think that spot is worth the money. You can get a product like this with no branding on Ebay priced reasonably.

The second thing is actual road noise coming through the floor and wheelhouse areas. For that you could use the factory underlayment with an additional layer of a dense material that blocks sound transmission like "Dynaliner" or an equivalent product. I used some heavy/stiff fiberglass matting that I split into thinner layers and glued it to the inside of my fiberglass side panels to help with the drone from the wheelhouses.

I already have a roll of flexible soft rubber that I am going to put over the factory stuff that will add a layer of density, I will let you know how it works out.

But, you kinda get the idea, covering the entire floor in a dynamat product is nice, but it is not really designed to stop sound transmission, its to stop new noise from being created, and many times people over do it.

I'm all for doing things on a budget. I completely covered the interior of my sons car (roof, floors, doors, trunk, quarters, etc. with an insulation product I got at Lowe's. Now before you with "that crap won't work"... YES it does. It's about a 1/4" thick, has the same jute backing as most modern carpets and is covered on both sides with foil. It cuts easily and lays down good. I used 3M spray adhesive to bond it to the car and it it quiet as a mouse inside the car. It's never gonna be LEXUS or Mercedes quiet because I have the 302 running nothing but glasspacks off the headers right now but I can sit in the car with the engine running and whisper to my passenger and they can hear it. http://www.lowes.com/pd_13353-56291-...Info=Reflectix
This is the stuff I used. at 13 bucks a pop I used 3 rolls and I covered everything. It not only acts as a sound deadener but it's heat barrier too.

I am in the process of doing mine also. I decided to go with the Lowes Peal and Seal. It lays down nice and sticks like crazy. I plan on going over it with Frost King duct insulation also from Lowes.

Smokeybear, I thought the reflectix was bubble pack with foil facing. Are you saying that its got a jute center?


FWIW Home Depot has sound barrier that goes behind drywall that can work really well on horizontal surfaces from what I hear. (No pun intended)

Yeah, the stuff I used has a jute center. It may not be the same name brand as what I posted. I found it in the insulation aisle.
