RAPTOR is a water tight coating once fully cured and can be used for many marine applications. Let RAPTOR cure completely for approximately 72 hours before immersing in water.
RAPTOR will also hide a multitude of problems, like crazing, pitting and scratches. Sand the crazed gel coat with 100-120 grit sandpaper before applying RAPTOR over areas, including below the water line. RAPTOR will perform below the water line for exterior protection but not as a water sealant. First, repair the damaged gel coat with FIBRAL (UP0717), FIBRAL LITE (UP0700), or SMC bonding filler (UPO777 or UPO779) to seal the surface.
