Right - under no circumstances should you ever use silicone in an electronic device.

A fellow I know showed me a box once that had been filled with electronics, then potted with silicone. The silicone had eaten away all the wiring. Not pretty.

Hot glue is a much safer solution. If the components can withstand the heat for a short period as the glue cools down, it will not affect the wiring at all.

As a matter of course, I pot every AC line bypass bakelite block I rebuild, to ensure the wires do not short together. I also dress the leads in such a manner that they are as far apart from one another as possible, and are also placed away from the terminal holes (unless the particular lead goes through a particular hole).
