Strongly pigmented, this shellac polish will produce an opaque black surface suitable for new and restoration work requiring an ebonised finish. Many fine pianos have been given a new lease of life with a smart new coat of black polish when their original has become dilapidated. Applied in the same way as all other French polishes by 'mop' or 'rubber' it can be built to a mirror finish or used on an open grain oak for an interesting textural surface.
