Lasting Corrosion Protection: Deposits a water-resistant barrier that delivers anti-rust and corrosion protection to guard bearings, pipes, conveyor belts, and exposed fixings against future build-up to extend service intervals between maintenance. Professional-Grade Performance: Engineered for mechanics, engineers, and professionals who demand consistent results, this industrial-strength penetrating spray operates across a wide temperature range for workshop, garage, and field applications. Precision Smart Straw Control: Reach tight spaces and awkward angles with the integrated Smart Straw for pinpoint accuracy, or flip down for broad coverage, the 360° valve enables spraying in any orientation, reducing product waste and time. Specialist Maintenance System: Pre-clean with WD-40 Specialist Degreaser spray, apply Penetrant spray to free seized components, then protect with White Lithium Grease for lasting lubrication, or add Cutting Oil for drilling and metalwork.
