ZAM compound provides a lustrous finish, yet doesn't require the pre-finish a rouge can. These versatile compounds allow you to polish most metals, softer stones, epoxies and plastics. Hint: Avoid surface drag lines on stone, epoxy or plastic by not letting the buff get too hot. Use with soft stones or any metal. It leaves a high luster without residue and does not cling to or penetrate the surface of stones. It can also be used as a final finish for gold. Sold in 114 gram tube
