Disclosed herein is a novel approach to producing a lightweight component. The lightweight component is produced of a much lighter material than has been used before, produced by a process of mixing a compound containing uncured silicone and a volume of microspheres, and then dispensing this material into a mold. Such a mold may be a female mold having the negative three dimensional shape of the lightweight component to be produced. The lightweight component may then be pressurized and/or heated during the curing process either prior to removing the lightweight component from the mold or after removing the lightweight component from the mold.
