S4P Lanolin Spray Liquid 5 Litre
Welcome to S4P Commercial Grade Lanolin
Born in the heart of rural Wales, S4P is a 100% natural, lanolin-based anti-corrosion spray that brings nature’s own protection to your tools, vehicles and machinery. Made from purified sheep wool grease, it forms a long-lasting, self-healing barrier that shields metal from rust, corrosion and moisture, without a single harsh chemical in sight.
Whether you’re working on the farm, in the workshop or out at sea, S4P is built to perform. It’s water-resistant up to 3000 PSI, won’t wash off under pressure, and keeps doing its job long after ordinary sprays have given up. Best of all, it’s completely non-toxic and eco-friendly, so it’s just as kind to you and the environment as it is tough on rust.
From axles and chassis to marine equipment and hand tools, S4P Commercial Grade is nature’s shield against rust, proven where it matters most.
