Step 1: Remove the boat from the water and turn it upside down if possible. Scrub away debris from around the damaged site with a wire brush. Sand the area with 60-grit sandpaper.

Step 2: Take a small wooden block, place it over the leak site, and hammer it to flatten the tear as much as possible. Then wipe the area with a clean rag soaked in paint thinner. Let dry.

Step 3: Apply J-B Weld compound to the repair area. Let sit for four hours. Paint the outside patch with aluminum spray paint. Sand the interior patch smooth and cover with silicone caulk.
