Protection First Class (PFC) penetrating lubricant and rust inhibitor represents company’s entry into a new category of environmentally responsible formulations, as indicated in a 99 percent pure 
cosmetic-grade lanolin composition. Traditional penetrating lubricants use solvents to lower the viscosity of the oils they contain, enabling them to flow more easily or to be dispensed as a spray. The solvents break down some of the essential properties of the oils they mix with and, after quickly evaporating, leave a dry, varnish-like residue that can collect dirt and may actually increase surface friction—thus impeding mechanical action.
PFC is different by design, product developers note, as it is solvent free, but formulated to spray easily and stick to surfaces tenaciously. As PFC is being applied, its high viscosity allows almost 100 percent of the product to stick to the targeted area. After application, PFC remains soft and pliable and forms a protective, friction-reducing film that delivers lubrication and anti-corrosion performance. In the case of small nicks and abrasions, the PFC coating will actually heal itself by flowing to fill small gaps in its protective surface, sealing out moisture and oxygen.
Protection First Class is completely solvent free and formulated with top-quality, virgin ingredients; the woolwax lanolin formula has been classified as a non-hazardous, nontoxic substance. The lubricant is packaged in a variety of container sizes, from 15-ounce aerosol spray can or 1-gal. jug to 5-gal. bucket or 55-gal. drum. — Berkebile Oil Co., Somerset, Pa., 800/732-9235
