CONDUCTIVE PAINT/ADHESIVE?

    I'm looking for a small quantity of inexpensive conductive paint 
or adhesive for use with metallized plastic parts in a potential 
microwave application.  I have a couple of ounces of silver bearing 
(>99% based on weight) pain in some kind of a nitrocellulose binder 
which I've been hoarding for almost 60 years but hate to use it if 
something less expensive is available.  Seems to me there must be, 
probably copper based, but a quick look hasn't turned up 
anything.  Any clues?  I'm not intending to coat terminals or 
anything like that, just make electrical connection between brass 
waveguide and plastic parts.  Need enough strength to permit safe 
handling but may be able to accomplish that part by overcoating with 
epoxy cement.  Any suggestions welcome.
