Hi, I’m making an acoustic guitar and wanted a copper looking inlay around the sound hole.
I have routered a 120mm diameter ring, 6mm wide by 1.5mm deep and poured clear cast epoxy mixed with the copper pigment in. However when it’s dry and I scrape/sand it just stays a dull brown colour.
There are small parts on the overspill that go a bright copper finish, but the inlay doesn’t.
Any help would be much appreciated, many thanks.
