PROTECTING MAPS AND CHARTS: Spread the map or chart face down on a clean flat surface on a newspaper or other clean paper. Spread Nikwax Map Proof on the surface with a clean cloth or paper towel, making sure to spread to the edges and in the folds. Wipe excess away. Allow to dry, it is helpful to hang the map or chart and newspaper over a chair or line. Proof the other side by turning over and applying Map Proof. Again, hang it to dry. #NIK521
