Hydro-lok Super Hydrophobic Nano Technology Liquid Repellent

Rainguard Hydro-Lok contains revolutionary technology that repels water, mud, ice and other liquids and protects against corrosion, wear and stains caused by exposure to the elements on a very wide range of fabrics, canvas, leather, wood, masonry and other surfaces. Hydro-lok is a single component nano-based super hydrophobic treatment that creates a moisture barrier on almost any surface.

Hydro-LOK does not contain any harmful solvents and is not flammable either in liquid or dried form. Hydro-lok is completely clear when dry and does not create a dark, hazy or frosted appearance. It is packaged in an easy-to-use sprayer, not a pressurized aerosol can. Hydro-lok creates a clear, deep-penetrating and non-film-forming chemically reactive water repellent that contains no silicone oils, paraffin wax or urethane.

Hydro-lok comes in a 16 oz plastic spray pump bottle and a case of 4 bottles or 12 bottles for additional savings.
