Aluminum boats lead hard lives. They get beached, hit things submerged in the water, and tend to be used for many years. Over time, rivets and seams develop leaks, cracks or even holes. A leaky aluminum boat can sink quickly. Most existing repair products are tedious and time consuming. Their instructions require you to coat the underside of the boat. They don't handle flex or stress well, which leads to cracks and failure of the repair. TotalBoat Aluminum Boat Leak Sealer is different. It's the fast, easy way to repair leaking rivets, cracks, seams, and holes in your aluminum boat. It comes in a handy cartridge that fits in a standard caulk gun. Just pop the cartridge into the gun, attach the included mixing tip to the cartridge, point, pull the handle, and discard the first 3-4 inches of bead. After that, Leak Sealer comes out mixed at the exact 1:1 ratio so you get a proper cure and a waterproof seal. It’s that simple to get the right mix—and reliable cure—every time If you live in a colder climate, you’ll appreciate the fact that you don’t have to wait for the weather to warm up—you can apply Aluminum Boat Leak Sealer when the aluminum surface and the ambient air temperature are as low as 40°F, as long as the aluminum surface has been prepared properly. Aluminum Boat Leak Sealer is sag resistant so it stays where you put it, and won’t drip out of seams and holes. Gel time is 40 minutes @ 72°F. Flexural strength is 8,800 psi. Compressive strength is 7,200 psi. Paint over cured repairs for maximum protection. Wait 7-10 hours before sanding and painting. Wait 24 hours before subjecting cured epoxy to high loads.
