Woolwax is a lanolin based auto / truck undercoating made from raw woolgrease.. Woolwax sprays on wet and does not dry. Woolwax creates a thin lanolin film barrier to keep moisture and oxygen away from the base metal. * Woolwax has almost no smell. * Solvent free. Environmentally friendly. * Always active and creeping into inaccessible areas that rubberized coatings would never get to. * Woolwax is self healing if it gets scraped by road debris. * Woolwax will thicken to a gel film after applied and is very resistant to wash off. * Provides vehicle undercarriage protection for up to 2 years.. * 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 "honey" color, but when applied appears fairly clear.. 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. Note: Because Woolwax is formulated thicker then other undercoatings to prevent wash-off, it may be necessary to heat Woolwax a bit before applying in the colder weather.. This is easily done by just placing the pail in front of a floor heater for 5-10 minutes. Proudly manufactured in U.S.A.
