Leaking rivets and seams can easily be fixed by using TotalBoat Aluminum Boat Leak Sealer.
The metal within 1/2" of the repair should be sanded just until it is completely shiny. Remove any sanding residue, and etch the area with TotalBoat Aluminum Boat Etch Wash, as directed on the bottle, for maximum adhesion to the metal. Apply a bead of TotalBoat Aluminum Boat Leak Sealer around the leaking rivet or seam, and smooth the epoxy around and over the rivet to seal it. Allow the epoxy to cure for at least 24-48 hours before use.
TotalBoat Aluminum Boat Leak Sealer should not be used as a stand-alone product to fix tears, or larger holes and punctures in aluminum boats.
