Use a sharp tool, like a small knife or a utility blade, to carefully scrape away any visible debris. Be meticulous and patient to avoid causing further damage to the boat's structure.

Next, focus on eliminating old glue residue. Over time, the glue used in the original construction or previous repairs can weaken and contribute to the rot. Use a sharp knife or a utility blade to carefully cut away any remaining glue. Work carefully to avoid damaging the surrounding fiberglass. If the glue is particularly stubborn, consider using a small wire brush or a wire scrubber to gently remove it. Ensure that you inspect the area closely to identify any remaining residue.

For a more thorough clean, you might consider using a mild acid solution, such as white vinegar or a specialized marine cleaner. These can help dissolve any remaining glue or old paint. Apply the solution to the area, ensuring it covers the entire surface, and let it sit for a few minutes before wiping it off. This step is essential to ensure that no traces of old materials remain, providing a clean slate for the repair.

After cleaning, it's important to inspect the area closely. Look for any remaining debris or residue that might have been missed. Use a magnifying glass if necessary to identify small particles or fibers that could compromise the repair. This thorough preparation ensures that the repair area is free from contaminants, promoting better adhesion and a stronger bond between the new wood and the fiberglass.

Remember, taking the time to clean and prepare the area properly is a critical step in the repair process. It ensures that the new wood and materials will adhere correctly, providing a solid foundation for the repair and helping to prevent further issues. This meticulous approach will contribute to a successful and long-lasting repair of the rotted wood in your fiberglass boat.

Use Epoxy or Wood Filler: Apply a suitable epoxy or wood filler to fill and repair the hole

When dealing with rotted wood in a fiberglass boat, one of the most effective methods to restore structural integrity is by using epoxy or wood filler.
