Liquid Kraken is a true marine grade graphene coating that is formulated specifically for gel coat and marine paints. The low VOC solvent based formula carries a high concentration of graphene oxide which forms a monolithic layer of protection one atom thick. This ultra slick finish is known to reduce water spotting by approximately 50%. Reduced water spotting is the number one selling point on why a boat owner would select a Liquid Kraken over a SiO2 based coating like Liquid Thor. SiO2 and Graphene based coatings have relatively the same level of gloss and durability. The life span of the coating will be a function of how often the vessel is used, stored and maintained. A general time frame would be roughly up to 12 to 24 months of protection before you would need reapplication.
