I recently bought this lacquer to replenish my small stock and it is indeed seriously good stuff for brass and other metals.
As a hobby, I restore and collect antique oil and gas lamps and certain other antiques, including Tantalus and your lacquer is brushed onto the various metal parts and no brush marks ever show up and it does not tarnish, like some other lacquers, especially aerosol types, which I no longer use.
