Goldseal Automotive

Heavy-duty underbody rust protection for vehicles and equipment

Goldseal Automotive is a heavy-duty, oil-based underbody rust protection coating designed to protect vehicle chassis, seams, and underbodies from corrosion caused by salt, mud, water, and harsh road conditions.

Engineered for NZ and Australian environments, it delivers flexible, long-term corrosion protection for vehicles exposed to beach driving, farm use, off-road conditions, and commercial fleet operation.

Unlike bitumen underseal or paint-based chassis coatings, Goldseal Automotive:

• Does not crack or become brittle
• Does not trap moisture
• Penetrates seams and overlaps
• Remains flexible under impact and vibration

Based on our proven industrial corrosion chemistry, this spray-ready coating displaces moisture, creeps into crevices, and forms a durable, self-sealing barrier over steel surfaces.

Suitable for:
• 4WD and off-road vehicles
• Utes and commercial fleet vehicles
• Farm and agricultural vehicles
• Trailers and boat trailers
• Caravans and campers
• Earthmoving and construction equipment
• Coastal and salt-exposed vehicles
• Mining and industrial machinery

Whether applied by mechanical workshops, panel beaters, fleet managers, detailers, or DIY users, Goldseal Automotive provides industrial-grade rust prevention in a practical, easy-to-apply format.
