Repair nylon/hypalon/neoprene with this tough bonding formula. Kit includes either hypalon or Urethane/PVC adhesive and a 6" x 12" either hypalon or PVC fabric to ensure long lasting repairs on dinghies, sport boats and other inflatable craft. NOTE: If you are not sure whether your boat or raft is hypalon or Urethane/PVC, contact the manufacturer. Typically PVC or Urethane is the same color on the inside of the material as on the outside whereas hypalon is different colors i.e. dark grey/light grey. An exception to this is red PVC or other boats colored other than grey or white shades.
