Woolwax

Woolwax is the trade name for Kellsport Products' line of lanolin-based corrosion inhibitors, produced in Fall River, Massachusetts. The brand's flagship formula uses woolgrease (lanolin) as the primary active, providing a self-healing, flexible wet film rather than a hard-cured rubberized coating. Woolwax products are sold directly and through automotive distributors, and have developed a following in rust-belt states among owners looking for a DIY-friendly annual undercoating option.
