I want to get rid of my spray etching machine as I'm not using it and would like to recoup the space. It works great; etching is done in a few minutes. It comes with ferric chloride and a small bottle of hydrochloric acid (low strength) to rejuvenate the etching solution. Technically the etching process is now copper chloride based but the speed is still the same.
I'd hate to have to throw it away.
PM when interested.
