Well, how about this recent direct cut disc set.

Just placed my order for the Stockfisch Records 'DMM-Dubplate'. It was released today on 2nd June 2020. This is the first commercial release of a DMM copper disc. Of course each disc must be cut individually. There are 5 tracks on the disc. All artists are those signed to the Stockfisch Records labe...

I found an easy solution, use wood glue.

Has anyone experienced copper oxidation of DMM discs after cutting?
I'm not talking about a few days later, but months or years.
Could you gold plate a few microns (metric) to protect the copper?
