Sound Insulation for SSPs

[NoDrama43]

I have zero asphalt smell. Dynamat would love for you to think you will die if you use anything else. It just isn't the case. Dynamat is wayyyyyyy over rated and insanely overpriced. The stereo guys that are reps for them have no problem touting how great it is because they are selling the product and making money off you when you buy it. I bought my Dynamat off an eBay seller but it was still overpriced. When I was looking for something on the truck I did a bunch of research and found that a whole bunch of people use the less expensive stuff and like the results. My paint guy here in Ohio has been building high end expensive hot rods for 20 years and the stuff he gave me to try is all he uses. It is thinner than Dynamat but also has the foil reflective covering so I double layer everything. I also put new ACC (yuck) carpet in the Comanche and in addition to the sound deadener / heat reflective shield I used a very thin layer of a closed cell foam to help make the carpet fit better and also absorb some more noise. It turned out very well. I have a partial roll left in the barn, I will get you the name of the product tomorrow and send it to you.

I did say some ( meaning not all) have the asphalt smell. Just saying with some of these guys in hotter climates than say Ohio or even GA it would be an issue. Just putting this out there so they can do there own research and to be sure they've made the best choices for them. Being my own bodyman I personally did not wanna chance having to take up something that would be annoying to me and a PITA to get up. I'll be doing my 67 fastback soon and will stick with the dynamat for certain...To each there own but I choose to spend a few extra bucks to be on the safe side...

But with that being said I'm sure they're others out there cheaper with similar results

Thanks everyone for the information and opinions. Jim did you use Peel & Seal? I have heard that is sold at HD and Lowes.

Here's that closed cell foil backed insulation material you can get at the hardware store that I used to replace a ruined section of factory insulation on my roof. I had to glue it up there myself but twelve years later still having no problems with this thrifty and effective solution.

I've been doing more online research and I am considering trying a product by Noico that is 80 mils thick, less than $2 per square foot, and is available on Amazon. There are 200 reviews, 5 stars. It seems like a good compromise between the very low end and the Dynamat, that frankly, is hard to justify the cost. Perhaps if I was an audiophile and needed to build a sound car, but that's not my application.

I really want to do the roof, but I will not do the trunk because I want to keep it original.
