Just talking about this today. Heavy dynamite is good for heat and noise suppression, they also do a ‘foam’ that is self adhesive and goes over the top of the heavy dynamite. The guy I was talking to did this in his shoebox ford and really rated it, ‘like driving a rolls Royce’ were his words. He used the thickest foam, and cut channels in it to run wiring.
The dynamite ‘lite’ on the other hand is rubbish for street cars if you are doing it for noise reduction, as it’s a race car product, designed to keep heat out, noise secondary. Non of its cheap tho.

I did a dynamat knockoff topped with the foil looking bubble wrap stuff. I'm sure the difference would be noticeable if I didn't have the exhaust dumped out the side. As far as heat goes, I would have to believe its much better. Unfortunately I have about 20 years between the before and after result. I really didn't like adding the weight of the dynamat but figured having better comfort for passengers would be a plus.

I researched this alot when I was building my 55 truck. What I found was that a product made by Noico to be better in my opinion than dynamat. It is a little thicker and they also sell a closed cell self adhesive foam to put on top of it.... It cost less than half of dynamat you can order it from Amazon.

Phil, that is mighty generous of you to offer. I greatly appreciate your offer, however, since social distancing will prevent me from delivering the car to you, would you mind having the car picked up, at your expense, in an enclosed trailer to be brought to you and you can do the work necessary and deliver the car back to me as soon as it is completed. I will need you to provide a detailed explanation of what you are going to be doing, along with certifications proving that you are competent to perform the work to Federally established guidelines. You will also have to supply me with a performance bond guaranteeing the work for a total of 10 years, and clearly state the pick up date, and return delivery date. Once you have all the paperwork in order, please submit to my attorney for his review. In the meantime, I would like it if you were to submit the material of your choice to an independent testing laboratory for performance testing.
Please stay safe, wash your hands regularly, wear a mask and gloves whenever you go out. Be careful, it is dangerous out there..

Has trouble with lighters.....
I thought that he couldn't find 2 sticks to rub together...
I have used the peel and seal foil backed roofing in a few cars, but they were roadsters. Not sure if there us any out gas or not. 
The one car sat in my basement for a long period of time with no smell but wasn't out in the sun.
