Your cart is empty.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. Compare to West System G/Flex 650-K aluminum boat repair kit. With TotalBoat, there's no measuring, no mixing, no mess, and almost no cleanup. All TotalBoat products are developed by boaters for boaters, to provide great value and great results. We know what works and what doesn't.

2 issues:1. this is extremely difficult to dispense. I had to use a speed clamp on my calk gun handle to get it to come out.2. I laid down about 4 feet of this stuff and then noticed it changed color. This means it wasn't mixing the 2 parts together so all I got was 1 part of the epoxy which I now have to clean off so I can apply both parts and get a proper seal. I followed the instructions and considered the first 6 inches or so as waste since the two parts hadn't mixed and I assumed I was good to go. It's a great idea but doesn't seem to have worked well for me.That said, it seems like a quality epoxy so once I get it on the boat correctly I'm sure it will stop my leaks. I'll edit my review after a few days on the water.

Weather just got warm enough to use the aluminum boat leak sealer. Followed the instructions exactly but it took all my strength squeezing the caulk gun to get the product to barely exit the tip. Discharge was so difficult it would be impossible to lay down a consistent bead. Product components were not mixing properly either. Suspect I got a tube that had been sitting on the shelf too long. It is unusable and of course, I'm just past the 30 day return window. Very disappointed.

I can't speak to the durability of this product over time, since I just applied it. What I will say is it is very convenient and pretty easy to apply. I used this to replace the calk along the inner keel in the front of my aluminum boat. The self mixing tip was awesome. The directions on the packaging say the first 4 inches of product are considered waste. I would actually say it was more like the first 12 inches. The product will be tan in color when mixed, and after the first 4 inches it was briefly tan but then another foot or so of just the milky white portion before it went solid tan for the rest of the application. I'll have to figure out how to remove that section and redo it. Also, even with the tube at about 68 degrees, it was pretty dang hard to squeeze out with a regular calk gun. Finding one with better leverage would be ideal. We'll see how this works over time once I hit the water!

I had a slow leak on an all welded Tracker boat along the keel line. I bought this and put a bead along the entire keel and then smoothed it with my finger. Leak gone! Easy to use and the pre-mix tube tip works great. Per a previous review I saw, when you first start squeezing it out, wait until the color changes from white to a milky orange before using it. Great stuff!

I used this to seal some leaky rivets on a jon boat I recently acquired. Using a cheap caulk gun and the provided tips, it worked very well. It can be a little temperature sensitive so make sure you apply in conditions above 60 degrees. I did some application at that temperature and really killed my hand trying to squeeze the caulk gun trigger. I finished the job a few days later in warmer weather and found the application to be so much easier. The only thing to be aware of is that the tube can be a little misleading in size. It's only about 1/2 full, but I was able to seal every rivet on the bottom of my 14 boat, half the rivets on the inside, and several of the seams. It is however a caramel colored product and won't dry clear, so it will stand out that you've used it. That being said, it was perfect for my needs.

Had a small to moderate leak along the keep seem on my 16 foot riveted aluminum boat. Researched the Total Boat seam sealer as the best and most practical repair. Excellent epoxy working time allowed me to use a putty knife to smooth out the bead and press it in to the seam. Cures a milky amber color, but can be painted over. Retains a small amout of flexibility after cure to allow the hull to flex as it normally would. After two long days on the water, the seam seal held and allowed zero water in. My drain plug was dry on the inside after 7+ hours on the water, where I would normally have several gallons in the sump. One recommendation. Get a powered or heavy duty applicator. The epoxy mixing heads and the viscosity of the epoxy made it hard on the hands.

Very easy to use on my grandfather’s old aluminum boat that has been in the family for 50 years. Over time, a handful of rivets –and I’m surprised only a few of them came loose – have loosened up to create puddles in the floor of the boat that have recently gotten ominously larger. I was expecting the instructions to call for some sort of prep work, but this was actually the easiest repair I’ve ever done. All you need is a caulking gun and to wipe it down a little. No more leaks and the boat actually feels more ‘solid’ and less flexy.
