Best sound deadener

[JamesJ]

I just finished spraying my car with lizard skin, did both the sound control and the heat one, I will be posting some pictures soon of the installation, it went very nice and if you choose to use it feel free to ask me because if i did another car i could do it allot faster and just know how it work...

I used Lizard Skin spray on heat barrier on the interior of wedged, my Dakota project. I like the look of it and the speed of application. I would need to do some temp gun testing before I can give any real data.

How many sq ft do I need for the floor/firewall of my 69 Firebird?

Lizard SKin is some good stuff no doubt!
I have used both products. The heat coating is very popular and often confused with the noise coating. Many people don't realize there are 2 different products and they use the wrong one for the job.
The first coaitng Lizardskin came out with with the heat coating. It has been available for years and is a prooven performer.
The noise coaitng only came out about 2 years ago, but is doing pretty well.
Both are solid products.
I would not hesitate to use the noise coating if I did not have my own product (that I developed & formulated myself).

Keep in mind that with glass loaded thermal coatings the IR beam gun will not work. You will need a pronged temperature guage. One that actually makes physical contact with the material to take the measurement.

Depends on what your goals are and what product you use to accomplish those goals.

If you are trying to reduce road noise, engine noise, and exhaust drone, you will need at least 2 products.

One to reduce structure borne noise - (vibration damper)
One to reduce airborne noise - (noise barrier)

The floor is an important areas to hit but equally important are the wheel wells, quarter panels, firewall and doors.
Remember, road noise does not come from the road, it comes fromthe tires, and the tires are in line with the verticle SIDES of the vehicle. They are not inline with the horizontal floor. So treat the noise closest to the source will always be the best strategy when budget is a concern. The closer you can kill the noise to the source of the noise (tires or engine) the less noise will make it to y our ears.
So, treating the floor is important, but only after you have treat the areas closest to the sourece of the noise, folloing the path directly to your ears.
So, in order of importance

Wheel wells - front and rear
Quarter panels - front and rear
Rear Floor
Firewall
Front Doors
Floor
Ceiling

That is the order in which you should apply the material if you have a limited budget or a limited amount of sound deadening on hand.
If you can afford to shotgun it, then just do the entire car and be done with it!

But to answer your question, I can tell you want most of our customers go with.
It is a 2 part system (like I said above, one for structure bone noise, one for airborne noise).
The firewall and floor of your '69 FB can eat up the following amount of materials:

40-60 sq feet of a vibration damper is pretty common
30-50 sq feet of a noise barrier is pretty common as well

I don't want to come off like I am spamming my products so if you have specific questions about what Second Skin products use, let me know.
Otherwise, there are lots of solid performing materials out there that will work very well.

If you were to go with a noise coating, you would need about 3 gallons.
Remeber though. This woul donly address the first part of the problem. The structure borne noise. The coatings, no matter what they are made of or how good they are, will not address the airborne noise. This can only be done with a barrier. And for that, you will need to wait 30 full days for the noise coating to cure before applying a noise barrier on top of. See, coatings like Lizzard Skin and our nose coating Spectrum, are all water based and take 30 days to cure. If you apply any tupe of non porus priduct on top of the coating before it is fully cured, you run the risk of corrosion promotion. Too much water and you will start the formation of rust!
So be careful and do it right!

Hope that is not too much for you to absorb!

I have used the Spectrum spray product from Second Skin with much success on my '69 Camaro and am in the process of laying down their Luxury Liner Pro on the firewall and floor pan. Great customer service as well.
