Canoes commonly get damaged on their way to the water, usually by falling off a car top. Small holes and leaky seams can easily be fixed by using a variety of methods that work equally well on wood, plastic or aluminum canoes.
Small holes can be temporarily patched with duct tape. For the best adhesion, make sure the repair area and the tape are warm.
Remove any dents around the damaged area if possible. Dents in plastic or aluminum canoes are sometimes pushed out from the inside.
Coat the repair area with the resin mixture. Place the fiberglass cloth over the repair area. Saturate the cloth with the mixture. Smooth the cloth with a wood strip to remove any air bubbles caught underneath it.
