I am looking for an alternative to dynamat. Something readily available online. I have a aluminum center console for a humvee that I want to give a nice layer of material.

For the sticky stuff, I have used this and highly rate this stuff.

For sound deadening (Like door panels and under carpet) You're going to want closed cell foam, not the sticky stuff.

Amazon has many choices. Buy more than you think you need.
I used Kilmat on the RV and what was left on the Festiva. $65 for a box that should cover a vehicle.
I have experience with Kilmat. Worked good for me.
There was a comparison test a guy did a few years back. A product called brown bread if i remember correctly was one of Dynomats competitors. Do you have any car audio shops nearby? Many of them stock large quantities of sound deadening.
I use butyl sheets like the one linked above directly onto the metal, then closed cell foam on top (MLV maybe in the future.) CCF doesn't sound deaden anything, it's just to provide a layer between the butyl sheet and the mass-layer vinyl does that the sound deadening.
Lowe’s sells this stuff, it’s a roll of black sticky tar stuff with an aluminum backing. 6” wide, 20’ for like $20. It’s waaay cheaper than anything else out there. It’s a bit over 1/8” thick. It absolutely works. Truck smelled like tar for 3 months, and then pretty much any scorching hot day. I learned this is why people pay for the pricier stuff, however, on a budget, it worked.
Also, all the pics I’ve seen have folks doing 100% coverage. I don’t think that’s needed. The most important places are wear the metal can vibrate the easiest - out in the middle away from the edges. So, if you are on a budget, maybe go for the middle of the door panels, middle of the floor sections, but not so much where there are corners, curves and edges.

Isnt that stuff for frost insulation (Frost King)?
I used it in my F150. Works perfectly. Smelled for a week. Then no smell at all. Even in a black truck in Florida.
You could get some of the industrial sound deadening in a spray can.
I had replacement OEM doors installed and they had no sound damping. So I used it in those.
Way back when, my wife tangled with the parking lot bollards while making a RH turn. The kind that have a can-opener type top. They worked perfectly and sliced open the entire right hand side of the truck.
The stuff worked so well, I eventually ended up placing rows of it in side all of the doors.
What I should have done is use a bit under the headliner too. Maybe my next truck.
EDIT: To clarify, the OEM doors fit perfectly, and looked perfect. But they were really tinny and noisy. Noticed right away when driving home from the body shop. So I pulled off the door panels, sprayed the seams with Corrosion X and installed the damping material with great results.
Kilmat is what I have used a number of times, and its pretty solid stuff.
