Klean Strip Boiled linseed oil is a classic wood finish and natural protectant that is produced from the seed of the flax plant and processed so that it will dry faster than raw linseed oil. Boiled linseed oil protects and seals unfinished wood surfaces and produces a beautiful hand-rubbed finish on fine wood and antiques. | Klean Strip Boiled Linseed Oil | Size 5 Gallon
