Search for pcb potting compound. Its stocked at most electronics suppliers, usually comes as a two part epoxy that you mix and apply. It provides your board with protection from damage / heat / water, and to some extent hinders reverse engineering, however you can always remove the epoxy with the right chemicals, so dont count on it for that.
