Woolwax Lanolin undercoating. (4) Quart Bottles. Ready to use. No messy filling. No messy pouring from gallon pail to bottles. Woolwax Quart bottles full and ready to spray. Woolwax is formulated to be thicker than any other lanolin based undercoating product. Woolwax has almost no smell. We have neutralized the strong woolgrease odor with our proprietary process. Woolwax is formulated with more raw woolgrease (lanolin) than any competitive product. That makes Woolwax considerably thicker and more resistant to wash-off for longer protection. Woolwax can be applied with most undercoating guns using 70-90 psi. Since Woolwax is formulated thicker, in cold weather it may be necessary to heat up the Woolwax before applying. This is easily done by placing the container (bottle, pail, etc) in front of a floor heater for 5-10 minutes. After warming, stir well. WOOLWAX is a lanolin based auto / truck undercoating made from raw WOOLWAX. WOOLWAX sprays on wet and does not dry out. WOOLWAX creates a thin lanolin film barrier to keep moisture and oxygen away from the base metal. * Solvent free. Environmentally friendly. * Always active and creeping into inaccessible areas. * WOOLWAX will thicken to a gel film after applied and is very resistant to wash off. * Provides vehicle undercarriage protection for a full season. * Enclosed areas (doors, frame-rails, rocker-panels, etc., that are not exposed to road-wash will be protected indefinitely (years). This is the advantage of no solvents. There is nothing to dry up and evaporate. WOOLWAX is a very clean product as opposed to messy black products. WOOLWAX is a non-drip formula. We make it to be as thick as possible to resist wash-off, yet still easily sprayable. WOOLWAX can be applied with most undercoating guns using a pressure of 70-90 psi. Proudly manufactured in U.S.A.
