Lizard Skin (maybe?)

[zigmont]

I wanted to create a sound deadener and insulating layer for my 65 Mustang, so I created my own insulating paint by mixing microspheres with latex paint (similar to Lizard Skin) I put it on pretty thick, so it took a while to cure completely. I am very satisfied with it except you can scrape it off fairly easily.
I have another project I will be working on early next year, so I am thinking of making some more insulating paint using some acrylic enamel that I bought and didn't like the color. I figured I could mix the microspheres and acrylic hardener with the paint and get something that would cure pretty fast as well as it would get very hard and wouldn't be easy to scrape off. The only downside I can think of is that it would be flammable to some degree, and the latex is not. I considered using Dynamat, but you can't cover everything completely, whereas I can spray the paint into all of the nooks and crannys where the Dynamat can't be used. I am considering using both.
Has anyone ever tried anything like this before?

Just out of curiosity:
What material are the microspheres made out of?
How are these spheres expected to dampen sound?

You don't need it in all the nooks and cranny's. Most of the noise that will come in the car are the thin flexible parts of the car. Like putting it on the rockers is a waste. "anyone who wallpapers the whole car has watched too much TV." - Dynomat employee.
The one person that I know use the lizard skin said they were unimpressed, and pissed they had to buy the gun and other thing to use it.

Microspheres

They are made of ceramic material. They are so tiny that they will blow away like dust in the wind. You need to use a mask when mixing them in the paint medium so you do not inhale them. I think that they are mostly used as an insulator, but the manufacturer has a sound deadner version as well. (See Link)
