Proven cure for dry rot. Penetrating adhesive-flexible sealant - restores strength of rotted wood. Pours into the finest openings, penetrates deep, and completely saturates rotten wood, arresting the progress of dry rot by encapsulating the fibers. It subsequently cures into a tough, resilient adhesive that bonds wood members together with a mass stronger than the original wood. Ideal for wood encapsulated by fiberglass such as transoms, stringers, keels, etc.
