How durable is a lacquer finish?

Durability, Appearance and Affordability Lacquer is tough. It lasts as long or longer than any of its competitors without flaking or chipping. Lacquer remains clear for years without the yellowing usually associated with varnish, polyurethane or shellac.

Is lacquer finish waterproof?
