Have done both. Dynamat all the way
Would you mind telling a little more?
What reason or reasons do you prefer Dynamat?
I used Dynamat on my '70 years ago, I liked the results, but I have wondered if a spray on product would do the same.

The Dynamat flat out works. Not the off brand stuff either. The Lizardskin requires more surface prep and it just doesn't work as well. You have to get two products, one for heat and one for sound. We will still use it if a customer wants it but almost all wish they went with the Dynamat
I did not know Dynamat worked as a heat shield too...

As a side topic, are there any quick/easy things you can do to get the noise levels down for now----(don't want to do a full sound deadening project, taking the interior apart etc. just yet)
What about the vent windows?

vent
if vent windows are making noise you probably need new seals..if your window lock isnt pulling it closed enough you can work on lever

As stated for the vent windows, new seals... or caulk those bitches shut and don't use em.
I did not like the price of doing dynamat for my '91 crew cab. It was going to cost a fortune to do it all. Dynamat works great, no question about that. I instead used a roofing product called Grace ice and water shield. Totally odd way of doing things but worked great for me. It's a waterproofing membrane used in roof valleys and along eaves or other problem areas. It comes in a roll just like roof felt and has a self adhesive back. It's fairly thick and installs like dynamat. I had a half roll after a roof repair and thought I would give it a try. It was enough to do 2 layers on the entire floor. I used the rubber floor from LMC instead of carpet on top. I am really happy with the sound deadening and my floor is completely waterproof from the inside. No worries about mud and snow soaking off my boots. Real quick web search (Amazon and home depot) has dynamat around $4 sq ft and grace about $0.62 sq ft. Even with 2 layers it was way cheaper than dynamat. It's probably not as good a sound deadener as dynamat but I am completely happy with how my truck turned out.

I don't know if I would call it heat shield, but they have one that helps with heat transfer. That is what I used on the floor of my '70.
I picked up some of the Al's Heat and Noise reducer. I have some rust spots to deal with before I apply it so it'll be a while before I get around to it. Gonna go with that from the firewall to the tailgate, do the inside of the beds, wheel wells, and then probably some hush mat or dynamat on the inside of the doors and tailgate to just eliminate ratlles all over.

lets us know how it turns out
Wanted to bring this back up for a question I have about dynamat. Do any of you that have used it know what happens if it gets wet?
I've been considering it for use on a firewall under the hood but there is a good possibility it will see mud and water occasionally and I would hate for it to soak up and hold water. Mostly considering it for heat reduction.

I believe that it would depend on how well you can get it to adhere to the panel.
If it had a perfect seal with the adhesive, it should be good. The mat itself is an asphalt based material, so it wouldn't soak up water, the concern is trapping it.
Just my opinion/experience.

I put the Xtreme version on the floor in my '70, and the original in other areas. A heat gun helps immensely, but use leather gloves and a roller too.
