1. Hole Preparation

Begin by preparing the damaged area by enlarging the hole slightly using a drill. This enlarged hole will accommodate the aluminum patching plate.

2. Patch Plate Creation

Cut a patching plate from the aluminum sheet, ensuring it’s slightly larger than the enlarged hole. Smooth the edges of the patch plate with sandpaper.

3. Patch Plate Installation

Position the patch plate over the hole and secure it with a rivet gun. Ensure the rivets are spaced approximately one inch apart. Countersink the rivet heads slightly using a countersink bit.

4. Sealing the Riveted Joint

Apply a generous bead of marine-grade sealant around the perimeter of the riveted joint. Use a clean cloth to smooth out the sealant, creating a watertight seal.

5. Finishing Touches

Allow the sealant to cure according to the manufacturer’s instructions. Once cured, lightly sand the repaired area to ensure a flush finish. For added durability, consider applying an additional layer of sealant over the patch plate.
