Inox MX3 is Australia's original multi-purpose lubricant — trusted by boaties, tradies and outdoor enthusiasts since 1984. The unique non-petroleum formula penetrates deep into metal surfaces, displacing moisture and forming a long-lasting protective film against rust, corrosion and seizing. Unlike petroleum-based sprays that wash off in wet conditions, MX3 stays active even when submerged — making it the definitive choice for marine, coastal and outdoor applications.

MX3 is safe on rubber seals, O-rings, plastics and painted surfaces — which means it can be used on outboard motor components, trailer winches, electrical connections, fishing reels, hinges, bike chains and anything metal that takes a beating in the outdoors. The 300 g aerosol is the most popular size — enough for a full seasonal service of trailer, boat and camp gear.
