Obenauf's Heavy Duty LP is one of the finest all-around leather dressings we have found. It is an all natural product made of three naturally occurring oils suspended in beeswax and Propolis. Obenauf's repels water, acids, petroleum, salt and chemicals, restores and preserves dry leathers, prevents rot, and resists mildew. We recommend it for all smooth leathers. Apply by rubbing it in with a cloth by hand and allow it to absorb. Obenauf's provides an excellent water barrier that lasts longer than other boot dressings while it renews the appearance of even badly worn boots and shoes. Please note that application of Obenauf's can darken the leather.
