Zinsser Bulls Eye Shellac is an alcohol-based solution of lac, a natural resin imported mainly from India and available in clear and amber tones. Clear shellac dries transparent with a faint, golden cast that is much lighter than oil-based varnishes, while amber shellac has a warm, orange cast that gives a rich, antique look to woodwork. Zinsser Bulls Eye Shellac has many advantages over other clear finishes: it’s easy to use, dries quickly, is non-toxic when dry and cleans up easily with ammonia and water. This finish beautifies wood with a lustrous glow that won’t darken or yellow with age.
