Aluminum Boat Leak Sealer Marine Adhesive | Thickened Epoxy Adhesive for Flexible Bonds; Repair and Seal Aluminum Rivets, Cracks, and Seams; Fits Standard Caulk Guns

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.

I bought this product to seal loose rivet leaks in my aluminum boat. I have not put the boat on the water yet, so cannot comment on how well it worked. That's why I gave it four stars and not five. I gave it four because the product was delivered promptly including a card asking for comments and offering a 20% coupon for future purchase as well as a product support phone number. Very nice service offer that at least appears as if the company - TotalBoat - is concerned about customer satisfaction. The product came well packaged and included two dispenser tips and a container that fits any caulk gun. Other comment had me a bit worried about being able to dispense the epoxy because I don't have great hand strength, however, cautioned by instructions on the tube I laid it in front of a heat duct while I prepared the surface and then had no trouble dispensing it at all. It was easy to get out of the tube, emerged as a not overly thick and easily pliable liquid that was very easy to manipulate, and ultimately made a nice layer that looks like a good seal. I applied it to rivets in the boat's floor then again on the bottom (so overhead). It stuck and stayed well in both locations. I've used Gluvit before and been very happy with it's property of filling in along the shaft of rivets as well as over the ends. This product is a little thicker, but it also had some flow so I'm hoping, but can't say for sure, that it did the same. In a week or two after I've finished this repair and installed the new floor, I will put the boat and the water. If it works as I hope, I'll change the rating to five stars. If not - well, you may see a new message in this space, but from all appearances I expect it to perform well.

Worked well. I used it to seal a leaky riveted seam where the bottom of my aluminum boat meets the transom. Followed the instructions regarding surface prep, no problem squeezing it out with a standard cheapie caulking gun. Came out thin enough for me to force it into and through the seam with some compressed air, then gave it a thicker bead inside and out, then had plenty of time to smooth it. Took paint well. The following week, took it out to the lake, it sat in the water for 6 days with an hour or so of driving around each day, and no leaks at all. Very satisfied.

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.

The resin was half empty in the tube, had to waste half of the hardener trying to get it to flow. Once flowing, put the tip on and applied. It didn’t mix correctly, did not harden and was difficult to remove.

Worked perfectly and was easy to apply.

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.

It is easy to use seals well

Absolute Garbage. Mixer tubes don't thread on properly. Decided to mix product by hand and it never set up. 2 part epoxy my axx. Total waste of $110.00. Never buy this crap.
