Sound insulation question.
I'm thinking about adding some sound insulation to my 01 F250. I'm hoping some of you have some experience with this and can give me your opinions and / or tips on how to go about it.
So far I've learned there is Dynmat and similar products, and something called "quietcoat" that sprays on.
Has anyone been through this process before? Where you happy with the results?

I have no experience with spray on insulations but have been told they don't really work. I just finished using Dynamat on our new Mustang from the rear seat through the trunk and it made a big difference. The only thing is it is expensive.
The only advice I can give for installation is it works best if its warm as the Dynamat is very plyable. Let it sit in the sun for a little bit before you apply it.

What type of material is Dynamat? or, atleast what is it similar to?
My buddy had the idea of using rubber membrain that people use on RV roofs and such. It's basically just a 1/8" thick sheet of a special rubber material...

Dynamat material reminds me of a real flexable piece of tar paper that goes on a roof. It is fairly expensive but worth it in my opinion, we used to use it in our vehicles when I used to compete in stereo competition. The spray on stuff does not work.

Yes that is what it is but about its over twice as thick as the stuff you can by from say Home Depot. But it also cost 5 times as much.
You are also correct that different materials work better at different temp settings. I'm not an expert at this but a friend at work is very good at this stuff. The biggest thing you are doing with Dynamat is change the freguency in which the panels vibrate to the lower range. Its the density of the material that makes the difference.
There are other products as good as Dynamat but you must be careful. There are also alot of copy cats that are not. With alot of copy cats you need more than one layer to achieve the same results and at that point cost is about the same.
One area to pay attention to is the transmission tunnel. I never noticed how load the tranny was until I did the back part of the car. Now I need to decide if I want to do the rest of it or not.

Dynamat Original is tar based. The newer better version, Dynamat Xtreme, is an butyl composite...

Dynamat Xtreme is VERY expensive if you pay full retail prices. You can get it on eBay for 1/2 off retail. A 36sqft bulk pack on eBay can be had for $120 shipped ($250 retail).
