ShellTech Underwater Coating 50ml
ShellTech-UC can either roll on with a firm sponge roller or can wipe on with a microfiber cloth to create a super thin barrier against barnacles and tube worms. As it is not an antifouling coating, it does not repel growth. It makes the surface super slippery so growth falls off once disturbed by moving water, a brush or just wiping with your hand. Great for underwater lights, running gear and fiberglass. Like ShellTech, it seals the surface you apply it to and helps prevent water penetration below the water line.
