In June 2004, KG was asked to formulate a water based etching material that would remove copper and leave other materials untouched. KG succeeded in doing this. KG-12 is a superior copper remover and this is the perfect product for those who choose etchants over abrasives. KG-12 is powerful and should be used by professional shooters only.
