HP Rustop 388 is a high-performance greasy film type rust preventive developed to provide long-lasting protection against corrosion for metallic components and precision-engineered assemblies. This product is part of HP’s advanced range of rust preventive oils that form a durable, waxy, and non-tacky film over metal surfaces, effectively sealing them from moisture, air, and corrosive industrial atmospheres. Unlike solvent-based rust preventives, HP Rustop 388 does not contain any volatile solvents, ensuring higher safety, environmental friendliness, and enhanced protection for both ferrous and non-ferrous metals. At room temperature, HP Rustop 388 remains in a semi-solid waxy form, which allows it to coat metal surfaces uniformly and create a strong barrier that prevents the ingress of moisture and oxygen. Its special formulation ensures excellent adhesion even on complex geometries, threads, or machined surfaces, providing a continuous protective layer that resists displacement during handling, storage, or transportation. The product offers excellent water resistance and prevents corrosion caused by humidity or contact with saline environments, making it ideal for use in coastal or humid conditions. HP Rustop 388 is particularly recommended for the protection of precision-engineered components such as piston assemblies, gearboxes, oil seals, bearings, transmissions, and timer chains. It is also suitable for safeguarding machine parts, cutters, tools, and other highly finished surfaces during storage or shipment. Its advanced rust-preventive additives provide superior performance in both short-term and long-term applications, ensuring that even after extended storage, treated components remain clean, rust-free, and ready for use without requiring rework or cleaning. The product is designed for application through brushing, dipping, or spraying methods, allowing flexibility in industrial environments. Once applied, the protective film can easily be removed using standard solvents or alkaline cleaning solutions before the part is put into service. HP Rustop 388’s non-staining property ensures that it does not damage or discolor metal surfaces, making it ideal for use on precision parts and finished components. Engineered with HP’s advanced formulation expertise, HP Rustop 388 provides exceptional corrosion resistance, ease of application, and reliable protection for metal components stored under varying environmental conditions. Its ability to offer sustained protection without drying out or flaking makes it a trusted solution across industries such as automotive manufacturing, heavy engineering, machinery production, and tool fabrication. By combining superior protection, ease of use, and extended durability, HP Rustop 388 stands out as a dependable rust preventive oil for maintaining the integrity and longevity of critical metal parts.
