Marine-Tex Epoxy Putty
This is a true marine epoxy, which can be used for bonding, filling, and repairing damaged wood. It works as well for fiberglass, making it ideal for bonding wood and fiberglass together. Featuring a creamy paste consistency, it can be applied on horizontal or vertical surfaces. The heavier body helps it to fill gaps and rebuild damaged components. For bridging holes, fiberglass cloth or any other sort of cloth can be used as a filler and strengthener. Finished repairs are fully waterproof, allowing this epoxy to be used below the waterline. Cured, this epoxy can be sanded, ground, drilled and tapped. It accepts paint and many other coatings well.
