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.

There's a bunch of nickel based paints used for all manner of EMI shielding.
Conductive epoxy is readily available (it's used for things like die
attach, and is silver loaded, I think). Silver's not all that
expensive.. $11/oz and an ounce is a lot in an application like this.
