Back when I had absolutely no use for it I read an article about
"potting", encasing in epoxy/plastic/whatever small electronic
circuits.  Whay would one do such a thing?  Well, if you were building
a very small point-to-point gizmo in a small enclosure and you want
to freeze everything where it is positionally (to guard against shorts),
it would seem like a good method. RTV (silicone sealant to u) might
work but I'd rather use something hard.

Has anyone had experience doing this trick?  Can you use garden-variety
epoxy?  I think I have seen ads for materials designed for this purpose,
any sources?  Special thermal characteristics required?  Pointers, hints
kinks, sarcastic comments solicited, preferably by email.

Thanks well in advance,
