So I am getting my seats redone by a local shop that is very reputable. Always working on Ferraris, Lambos, and even does work for major companies including Nissan's design division. They are really cool guys and love to talk forever about what they do. Anyways, the always use a product called R-Blox instead of Dymamat, claiming that it is thinner (and obviously is) and based on research does a better job at all that it is supposed to do (I don't remember the percentage). Anyone heard anything about it? Looking on their site, it looks as though they were at the last SEMA and involved in many competitions.
I haven't ever applied any materials like this before but didn't think it would be too hard and its not. I just vacuumed and washed the floor with soap and water. My main concern is where is it actually useful to put this stuff? Obviously on the floor to block out road noise but as far as behind paneling and doors and places like that. I dont need to completely cover behind the panels or in the doors do I? Just around the speakers?

Thanks
Justin

Does it actually serve a purpose to use that much?
Yes, and no. Any car will have more noisy parts. For examples you will normally get the best benifits out of sound deadening doors for road noise. Then floor, and last roof. If you want to go all out put it everywhere. As for the product itself I have not heard of it. Like most deadeners they use MASS to deaden. The more mass the more effective. I would say a thinner product would be less effective unless the thicker deadener just doesnt stick.

i heard that heatguns cause the sound deadening "bubbles" to collapse causing the material not to be as effective....?

bubbles? hmmm... The heat gun if heating extremly hot MAY bubble, which would mean you are heating it way to hot to apply. I would recommend a heat gun as well especially in colder climates. The deadener once heated should stick to your fingers like crazy.
 
Again, unless you are heating it to the point its melting it will not affect the quality of the deadener. Keep in mind the product must withstand pretty intense heat when a car is sitting in the middle of a parking lot which can easily reach over 160 degrees in a hot climate. Adding heat simply makes is more plyable and ensures a better bond.

The more I think about this, the more I'm not sure this is right. I think that it might have more to do with density then mass. Also the reflective/absorbsion properties of a material.
 
I put the Brown noise stuff on my old Corolla everywhere -- behind door panels, roof, floor, trunk. Everything was real silent even on the highway, and my stock stereo sounded 100% better. Sound quality became terrible to amazing.

Yes, and no. It has alot to do with the make-up of the materials to make the sheet (or liquid) For example, a 1" thick piece of wood will weigh less than a 1/4" piece of metal.

I imagine since the shop you are dealing with "local shop that is very reputable. Always working on Ferraris, Lambos, and even does work for major companies including Nissan's design division." they would know what is good. The more deadning, the quieter the car will be. Downside...weight eats up horsepower.

Beware of some asphalt products at home improvement. They will work well but could give you that tar smell on hot days :(

Ahh, I don't have any tar smell in my car and that stuff's been in there for years. I have about half Dynamat and half roofing stuff.
Yep, I agree, and that is why I said "some asphalt products".

Many sound deadening products that are specially marketed for cars are made with tar. Maybe they add other chemicals to counteract the tar smell :confused: (ie. make the tar melt at a much higher temperature)
