Lanolin is a unique organic substance derived from the wool grease coating on raw sheep wool. It is an all-natural, incredibly effective substance that acts as a moisture barrier and lubricant.

​

WoolWax® Undercoating Formula is a lanolin-based corrosion inhibitor developed solely to protect the undercarriages of automobiles and trucks. Our lanolin is blended with other proprietary agents to provide long-term corrosion protection. WoolWax® will provide long-term protection (annual application) against salt, liquid calcium chloride, brine, and all other ice-control agents used by municipal departments.

​

Most other undercoating products contain up to 70% solvent, which makes them very thin and watery. At very low viscosity, these products break down and wash off quickly. WoolWax® is solvent-free and very thick and viscous. It applies like a heavy latex paint, which makes it very resistant to wash-off. WoolWax™ does not dry. It remains soft and pliable and continues to be active, migrating into all the inaccessible areas.

​

Woolwax® contains much more raw woolgrease (lanolin) than competitive products. This makes Woolwax™ thicker and much more resistant to wash off. Thereby providing a longer period of protection for exposed undercarriage areas. Woolwax™ is a maintenance application. A Woolwax™ treatment will easily provide protection through even the harshest of winter conditions. Woolwax™ is extremely resistant to wash-off. Woolwax™ contains no solvents, so there is no evaporation process. In the protected enclosed areas (doors, frame rails, etc.) a single treatment will provide protection for an indefinite period of time (years). The exposed area of the undercarriage should be re-treated every other year or as needed, depending on use and geographic region (snowbelt area, etc.). In most cases, a Woolwax™ treatment will last 2 years. Some people do prefer to do a touch-up of the undercarriage every winter. There is no need to remove or power wash the existing Woolwax™. Simply rinse it with a garden hose to clean it up a bit, then apply a fresh coat right over the existing Woolwax™. Many of our Undercoaters suggest treating vehicles in the warmer weather so that the Woolwax™ creeps and migrates into all the inaccessible areas.
