A Rust and Corrosion Preventive for quick and effective corrosion control and vehicle undercoating. For use on marine hardware, battery terminals, electrical connections, tools, brass clips, all metal parts or surfaces exposed to atmosphere or salty spray. No solvents - environmentally friendly. Made in the USA. It takes 1/2 to 3/4 gallon to undercoat a mid size suv. Woolwax is non-hazardous. Note: If you are in an area with consistent road slush, we recommend the Woolwax undercoat, as it is a thicker product and more resistant to wash-off. Woolwax sprays on wet and does not dry. It remains wet to provide a protective film barrier to moisture and oxygen. Woolwax will easily provide undercarriage protection for 2+ years. The enclosed protected areas (doors, framerails, rockers, etc.) are protected indefinitely (5+ years).
