Do it all the time. I usally coat my h-bridges and SE's in epoxy. When
you mix your epoxy add a drop of food coloring or some other form of
color. It gives the epoxy a cool color. Just make sure it works before
you encase it in epoxy =) If you still want to be able to get to the
circuit you can use hot glue. Also you can coat the hot glue in a thin
layer of epoxy so your bot won't melt if you leave in on the dashboard of
your car on a hot day.
