Sound / vibration deadening opinions
I'm starting to put the Camaro back together... I'm been doing some research trying to decide on what sound/vibration deadening to use. I would appreciate anyone's experience whether it be good or bad. I want something that works and lasts. Thanks in advance.

Here's what I've done.
First Dynamat "like" through out the floor pan and fire wall. It's the super sticky 3/16" under layment. Then the double foil sided material with the jute in between the foil layers. Glue it down to the Dynamat "like" under layment. Then glue the carpet to that. I use 3M spray can glue.

Look at Resonix, Soundskins, or Sonic Barrier (from Parts Express). The last 2 combine a thin butyl layer similar to Dynamat, but also adds a layer of closed cell foam on top of that. On top of that, I'd do a layer of 1/lb per square ft Mass Loaded Vinyl. Probably the best place to get it is Amazon, there are people selling it on there with free Prime shipping (and 100ish sq ft, is heavy, so it's a great deal.) Avoid brands like Murder Mat, FatMat, etc.
Another great resource is the website for the (now defunct) "Sounddeadenershowdown.com" It will be up will Feb of 2020, but the owner retired.
Has a lot of good info on what to use for what purpose and how to implement it. Resonix has some posts in Strictly Sound Quality on Facebook, and may also on their website. You can also find some interesting info on DIYmobileaudio.com and there's even a sound deadener comparison thread, if you google it.

OR he meant to use a Dynamat-like product. AKA, a copy.

Sound Deadener Comparison
Resonix is a new company that has stepped in to fill the void left when Don at Sounddeadenershowdown.com retired.
I know the owner, but I am not affiliated with him. He spent quite a lot of time getting samples, and making changes until
he got a quality product at a very reasonable price. All deadener is not the same, even tho they look similar.

As of this posting, the SDS website was temporarily down for maintenance, but the owner had previously stated he was going to leave it up
until Feb. 2020.
Most people not in the car audio biz (or NVH/engineering) don't understand all the different products and their uses for reducing different kinds of noise.
Don had taken the time to break it down into easy to digest sections explaining each product, it's use, application, etc.
Nick at Resonix is filling the void left by SDS's closure, and is a very accessible person, on many types of social media.

I used and will use more of some stuff at Lowes called "Peel and Seal" at about 18 bucks a roll. It has stuck like glue to my floors and firewall in my El Camino. It is also sticking very nicely to the underside of my EC's roof and I will also apply some Peel & Seal onto the doors under my door panels.
People warned me that this material might have a hot day "road tar" asphalt smell but that has not happened. I hit a hunk of it with some heat out of a thousand watt heat gun to see if it made any smell. Nope. None at all.
All of these products need a very clean surface for best adhesion. The bare metal of my floors initially got several heavy coats of some sound deadener liquid stuff called "Lizard Skin". Then a clear coat of paint on top of that and then the Peel & Seal. With the jute carpet and pile carpet under the seats, only my doors make any noise. Sadly, my Legendary door panels to solve this noise problem are on back order until nearly September after already being on order with the Original Parts Group folks for a month.

Let's see - I got the EC back from paint in early December last year. I started on wiring and the Peel & Seal soon after that - so, maybe six months. I suggest buying a roll or I will send you a hunk of it. It's tough to go wrong at 18 dollars a roll. Seriously, LMK and I will send you a piece.

Why do car guys spend 10's of thousands of dollars on their hot rods, but cheap out on audio and interior? LEt me use a roofing product to sound deaden my car. Sure. Why? Because it's cheap. smdh.

I'm in the same position as the OP, looking for a good vibration damper - sound deadener - heat insulator
Two thing I have noticed. First everyone seems to compare these products to dynamat and second the only complaint I commonly see about dynamat is the price. Sort of tells me dynamat is the gold standard.
I have a garage full of harbor freight tools. I'm not the type to get hung up on designer label anything, I look for values and what works.
But have to agree with JayinMI here. Roofing materials by design melt in hot weather to help them reseal. I spend enough time chipping the tar out of my Datsun floor pans to fix the rust that method left behind. If I did a dozen cars a year I might experiment more, but at this point the added expense to use the right product just isn't that much. In my case the cheapest solution is going to be the one I only have to do once.
I'm not sure what products I will use but do plan on looking at Jay's links.

I totally agree with pop n wood. I want to do this once... just because something is expensive or inexpensive doesn't make it good or bad. I want something that works well, decent to work with and lasts.

If people used the correct products in their intended environment, you'd notice a bigger difference. But since most people just slap some "Dynamat" (which has become a generic term, like "Kicker" means sub box) on and think that's all there is to it, they think it's fine. But whatever. Usually on car forums everyone says "I want to do it once, and do it right" then proceed to go on about how they can do it cheaper with an inferior product.
Dynamat isn't (as much) the "gold standard" as much as it was one of the first, and most well known brand of sound deadener.
