Both of those probably would want to float on the epoxy, and also would be impossible to de-air (if that even makes a difference in this kind of application). Before trying that, I'd do a test run on something I don't care about, like a length of ABS tubing. To reduce the amount of epoxy needed, use a smaller-diameter and shorter piece of tubing. A test run to figure out how to mix it all up wouldn't be a bad thing, regardless of what kind of composite you decide to make.Would perlite or vermiculite help in sound deadening?
