Crep Protect Rain and Stain Protection is a protective aerosol supplied in a 200 ml can. It creates an invisible hydrophobic layer that repels liquids and helps limit staining. The manufacturer primarily specifies canvas, nubuck and suede as suitable materials. Shoes must be clean before application; test for colourfastness on a concealed area first. Apply the spray according to the label, outdoors or in a well-ventilated space. Keep the aerosol away from heat and open flame during use.
