 there automated ways of applying?  I would be more than happy to hear from
 vendors, but maybe they should respond directly to me.
 Thanks.

Hi Steve (cool name by the way...),

      You have SMT parts breaking off? I've used RTV to hold PTH components
down, but I can't think of what kind of SMT component it would be that someone
suggested you use RTV on...RTV by the way is basically a silicone sealant that
stays flexible. I've used such materials to apply to radial components laying
them down on the board in a dab of RTV. What kind of component is it that's
breaking off? Sounds to me like there's really a solder issue that you got on
your hands...
