Dick, et al, do you think silicone / silastamer (sp?) type materiual would be
safer as a "potting compound in such instances, or is there some other
material more appropraite for safety's sake?

Also, my thought is this:  Why not just leave the radial caps loose inside the
old can? Does someone fear that they will fall out?!
