## Overview

TotalBoat Aluminum Boat Leak Sealer is a two-part, waterproof epoxy in a convenient pre-mixed cartridge designed for quick, durable repairs on aluminum boats. It offers a long 75-minute working time, applies in cold conditions down to 40°F, and flexes to absorb stress from vibration and expansion. Ideal for sealing rivets, seams, and small holes without mess or complicated mixing, it’s the go-to solution for boaters who demand reliable, professional-grade fixes on the water.

## Description

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.

Review: Great product - 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.
Review: Excellent - 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!

## Questions & Answers

**Q: After you started using the tube, can it be sealed and used again weeks/months later?**
A: Yes, they give you two tips. The first will be used and will harden after use. The two part epoxy mixes in the tip. You can use the other at a later time and you can purchase extra tips for additional uses. It's a great product and applies easily

**Q: Can this be used on bottom of boat waterside??**
A: Yes.

**Q: I have a 1965 richline big day 16 will one tube do all the seams on my boat??**
A: It should be enough to seal anything below the waterline, unless you are talking about 1/4" continuous gaps. I did 36' of seams and only used 1/3 of one tube of epoxy

**Q: Can I buys extra tips?**
A: I called their customer service with a question about application, and mentioned I could use an extra tip or two. They answered my first question and mailed me two tips. Good product, and good customer support.

### ⭐⭐⭐⭐ Easy to Use
*by A***A on December 22, 2024*

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!
