Silicone spray is used to enhance the glide and travel of Shuffleboard Discs. With a quick spray to the bottom of each disc, play is improved via reduced overall friction. A special 6% silicone formula is meant to stay on discs longer and requires less product. The spray can be used on our Poly Courts and Mini Roll-Out-Court. For the full-size roll-out court, plastic beads are recommended in lieu of spray.
