Hammerite 4X Hammerite Underbody Seal 500ml

From Hammerite, the Underbody Seal 500ml is designed for exposed areas beneath the vehicle where added protection is needed. Applied to floor pans, inner wheel arches and chassis rails, it forms a smooth coating that helps shield these surfaces from water, salt and stone chips while supporting rust prevention.

The non-drip formula allows for more controlled application and contains Waxoyl to help displace moisture and seal against further corrosion. It also helps reduce road noise when compared with untreated bodywork, making it a practical choice for maintaining vulnerable underbody areas.
