Net Weight: 16 oz. (454 g)
Heavy-duty black rubberized undercoating offers durable surface protection without the mess or odor of asphalt-based products. The fast-drying formula leaves a flexible, smooth, uniform layer that won't crack, chip, flake, or peel off.
The formula seals out moisture and salt to prevent rust and corrosion and is paintable in 1 hour. The built-in sound-deadening properties make it ideal for reducing road noise and vibrations in wheel wells, underbodies, rocker panels, and more.
