Can I apply Marine-Tex in dry conditions on a below-the-water-line application?
Yes, the Marine-Tex is an excellent choice for repairing gouges or holes that are located below the water-line. Once cured, Marine-Tex is impervious to water and many chemicals. Since putties will go only where they are placed, be sure that the Marine Tex has completely encapsulated the problem area. It is a good idea to sand the perimeter of the repair so that the Marine-Tex achieves a grip on the solid surface around the repair.
