It is a silicone-based formula that repels water from mechanisms, joints, hinges and rotating blades to keep them running smoothly with minimal resistance. It works by coating surfaces with a smooth, clear layer of silicone that will stop residues from building up, while creating resistance to rust and damage. It’s perfect for use on a range of metal power and hand tools, as well as plastic, rubber and wood. Water Protective Silicone cuts through built-up resin, dirt and grime to break down residue and give you tools a shiny new finish.
