Hi Brendan

Have you tried PCB manufactures? they plate through holes in non conductive
boards all the time
your task should be easy.

I'm looking for a company who specializes in plating copper onto high
resistance conductors. The material I want to plate has about 100 ohms
across a strip about 2 inches long. Does anyone have recommendations?

Thanks,
Brendan

Not a problem. Just keep the current low until you have a "flash" of
copper. Once flashed, it'll plate like a piece of metal.

You could also flash it with electroless tin, but I don't think it'll
be necessary.

If you want to have it done, look for a place that plates flowers and
baby shoes. One hit from Google:

Float the boat in the acid and provide the current to drive the copper atoms
to the boat and you can do it. The rest is time for how thick you want the
copper coating to be.
I'll note that it won't be cheap to float the boat nor the amount of power
that you'll be needing to provide for the plating.

Not a good idea. As the copper is slowly consumed (rusts), a portion of the
effluent would be Cupric Chloride and/or Copper Sulphate, which are extremely
toxic to living organisms.

Do they make a marine wax/applicant for this purpose?

And tributyl tin isn't ?

Which is why they used it. Killed the barnacles, ship worms,
etc. Kept the ships bottoms relatively clean.

Its mean stuff

I've had cupric sulphate on my arm at an old abandoned turn of the
century mine. Itches worse than fiberglass insulation

Looks really beautiful when you see a pond of it makes the water look
bluer than blue and still clear. (then i found out what it was AFTER)

She do tingle, don't she?

Try taking a bath in it. It's said to be like climbing down an active
anthill naked. But once you rinse off, your poison ivy doesn't itch
any more. I used some (1/4" copper sulphate crystal dissolved in a
couple ounces of water) on my arm after a night's romp in the bushes
at Bonsall Lake. I had 3 small bumps. The poor girl had it inside and
out, all over her body. Both of us knew of its toxicity and survived
its use. I wouldn't want to make a habit of it, but it sure keeps the
oils from poison oak/ivy/sumac from spreading.
