Building on the trusted Mendent lineage, this brushable coating is engineered to tackle corrosion and stone chips while delivering noticeable quietness by dampening drumming and road noise. The result is a durable, long-lasting barrier that keeps the underbody looking and performing its best.

What makes this brush-on underbody seal stand out

• Proven protection against corrosion and stone chips—a tough coating that forms a resilient shield on metal surfaces.
• Non-drip, brushable formula—easy to apply precisely where you need it, with less mess and waste.
• Rapid drying for minimum downtime—get back on the road sooner while still achieving a durable finish.
• Water-resistant seal with no rust bleed-through—even in wet conditions, the coating blocks moisture from reaching metal.
• Excellent adhesion to metal—sticks firmly to chassis, door sills, guards, and fuel tanks for real longevity.
• Hiding power and neat finish—provides good coverage that looks clean and uniform once dry.
• Non-staining on rubber and paintwork—easy to re-coat over existing coatings without removal.
• Temperature and salt tolerance—designed to withstand extreme temps and road salt common in harsh climates.

Where to apply and how it protects your vehicle

• Primary applications—under guards, chassis, door sills, and fuel tanks where corrosion and impact from road debris are most likely.
• Noise reduction—the coating on interior door panels and nearby areas can help dampen drumming and road noise, contributing to a quieter cabin experience.
• Inside door panels—extending protection inward helps minimize rattle and resonance without adding weight or mess.
• Important caution—do not apply to internal floor structures, as the sound may be amplified rather than dampened.

Application tips and practical insights

• Prepare a clean, dry surface to maximize adhesion. Wipe away dust, grease, and moisture before brushing on the seal.
• Use a brush to apply a uniform coat, targeting vulnerable areas such as seams, joints, and edges for comprehensive protection.
• Allow the coating to dry thoroughly between coats if you’re layering for extra durability. The formula is designed to re-coat without removing existing coatings.
• One liter provides ample coverage for typical underbody protection, with enough flexibility to reach around fuel-tank pockets, frame members, and sill areas.
