Hammerite 5092946 Underbody Seal 1L - Heavy-Duty Anti-Stone

Hammerite Underbody Seal with Waxoyl (1L Tin)

Hammerite Underbody Seal is a heavy-duty, bitumen-based coating enriched with the active rust-inhibiting power of Waxoyl. This thick, brushable compound is designed for the most punishing areas of a vehicle's underside, providing a super-tough barrier that resists stones, water, and road salt. The inclusion of Waxoyl ensures that even if the surface layer is scuffed, the underlying metal remains protected by active rust killers. It remains permanently flexible, meaning it will not become brittle or crack under the constant movement and vibration of the chassis. This product is the definitive choice for long-term underbody preservation in harsh climates.

Automotive Industry Suggested Uses:

• High-Impact Areas: Coating floor pans, inner wheel arches, and fuel tanks on off-road vehicles.
• Heavy Commercial Use: Protecting the chassis of trailers and light commercial vans that operate in coastal or salted-road environments.
• Weld Seam Protection: Brushing over newly welded sections to provide an immediate, heavy-duty waterproof seal.
