First let me explain my question, then I'll explain why I want to do it this way.
I learned from this thread (http://www.hotrodders.com/forum/alternative-lizard-skin-103610.html) on the Hotrodders forum, that in general, sound deadening paints are basically a paint with heavy particles in them (ie. lead or similar). I believe the way these paints work, is that sound waves travel through the paint and hit the heavy pieces causing them to oscillate in the paint. While they bounce around in the paint, they are generating heat due to the resistance from motion in the paint, essentially taking the energy from sound waves and converting it into heat, thus reducing the waves energy, thus deadening the sound well.
My dad said in the past they used to do something similar for some projects he worked on where they'd have a sheet laid out of RTV with lead shot imbedded in it to deaden the sound. Thus the reason why lizard skin sells both ceramic paint (for its heat properties) and a sound deadening paint. The paints are most likely very similar with just the solids in them being different (one being ceramic, one being something a lot denser, lead perhaps.)
I don't know a lot about the chemistry makeup of paints and I wonder how much harder Barrys bedliner is, compared to say the generic latex paint that is recommended via the thread on Hotrodders. I want to know if mixing ceramic spheres or possibly some type of metal dust would 1) work okay with the bedliner and still cause it to keep its properties (aka strength, endurance, etc.) and 2) if it would still deaden sound. If the bedliner is too hard, the advantage of using ceramics in the paint would be possibly null.
Why am I trying to do this?
I have a Jeep and for many reasons including liquid and physical damage, I don't want a carpet. In 2006 I replaced the carpet and it turned out to be a mistake since I ruined the new one immediately also. I want to instead this time shoot bedliner everywhere and call it a day. By everywhere, I'm talking the entire interior including floor, side walls, pillars and roof (yep no headliner or interior trim either). I also want to sound deaden and suppress heat transfer into the cabin though.
These ceramic sound deadening paints are designed to be covered by a carpet afterwards, while in my case they wouldn't. They would probably be destroyed pretty fast due to solvents and oils that might be accidentally spilled, and also due to physical damage from boots and cargo. Bedliner is much stronger and is made to stand up to these things. I considered laying the ceramic paint under the bedliner, but I have heard the ceramic paint has poor adhesion and I don't want my bedliner peeling up or sliding around under my feet. Ideally I'd just lay bedliner, but I've been driving around for the past year without any interior trim or carpet and the immense amount of sound is extremely annoying. Bedliner itself may dampen the noise, but it wouldn't compare to a true sound deadening paint. How can I have the best of both worlds?
