Description
Bilt Hamber Dynax-UB is a professional-grade underbody rust protection wax designed to provide long-term corrosion defence for vehicle chassis, floorpans, wheel arches, and other exposed areas. Formulated to displace moisture and arrest existing corrosion, Dynax-UB forms a tough, flexible, and self-healing black film that resists abrasion, salt, and road spray.
Ideal for use on both new and classic vehicles, Dynax-UB creeps into seams, panel joins, and welds to protect vulnerable areas that traditional coatings might miss. It’s compatible with factory finishes and can be used over sound existing coatings, as well as directly on bare or prepared metal.
Unlike thick bitumen-based products, Dynax-UB remains stable and easy to inspect or remove for future maintenance. It’s perfect for restorers, off-roaders, and anyone seeking durable, effective underbody protection.
