Seventy five bucks for a thimble of silver epoxy is ridiculous.

This is not the space shuttle  or a computer board here---copper epoxy will
perform just as well.

Buy youself some copper powder and make your own.  Some experimentation may
be necessary, but the electrical characteristics are certainly close enough
to do the job.

Mix the copper separately in the epoxy and in the hardener that you regularly
use in your layups.  Really load it up--the grains need contact with each
other.  Then mix up a test batch.  

By the way, has anyone tried threading the wicks and tapping the hole they go
into?  You could spray a little powdered graphite or copper powder into the
hole and on the threads and screw them in.  A little locktite on the last
thread or two would secure the assembly.
