Ballistol Universal Oil offers a wide range of applications in car care, especially in winter: It prevents door and trunk locks from freezing and door seals from freezing shut. It also protects chrome parts, rims, roof racks, and snow chains from corrosion and aggressive road salt. Because the oil is based on medical-grade white oil, it keeps rubber seals elastic in the long term, prevents them from becoming brittle, and makes the material look like new without damaging it.
