The rustproofing Seaflex Black is a product formulated with active ingredients to protect cars against corrosion. Composed of corrosion inhibitors and asphalt, it protects metal surfaces constantly exposed to moisture and water. Its gelatinous consistency makes it easy to apply by dispersing the product in the tiny places where water could accumulate. A flexible barrier is created and the product stays in place without ever flowing down. Its fruity smell makes it pleasant to use during and after the application. The rustproofing Black Sealflex is primarily used on areas that are exposed to the weather. It can also restore at the same time a new look to damaged black chassis. It provides effective protection for up to 2 years.
