Spray the product on areas of about 50 cm² at a time, then go over with a soft brush or sponge, rinse and dry. For best results, we recommend, after treating the dinghy with New Magic, the use of one of two protective waxes: New Gum Cream or Gumemp100. For frequent washing or new and/or lightly soiled boats, we recommend diluting the product up to 100 percent with water.
