The microscopically small nanoparticles form an invisible coating that gives the ultimate protection against rain, all types of stains and dirt penetration while still allowing the materials to breathe. It also provides UV protection so helps prevent items from fading. Dasco Nano Protector is suitable for use on a wide range of items - from footwear to tents - and on all types of leather, wool and fabric surfaces (including TEX Membranes). It is highly recommended to apply Dasco Nano Protector to new items before using them and then at regular intervals thereafter. 300ml Aerosol
