Will use again


At first I was skeptical about the product. I used my caulk gun that I use for everything and it was very hard to push the product through the tip. I also was concerned about the color. For whatever reason I was under the impression that it would be a grey color. It's not, which is ok. I wasn't able to get it in the inside of the seam where I would have liked to put it so I ended up putting it the outside of the seam in layers. I believe it will hold. I has hardened to a very strong feel. I sanded down the existing paint to the bare aluminum and it has adheared very well. Only time will tell.

If I ever needed this again I would buy it.


This went on and hardened great, I have an older boat that we welded most of the holes up but the seems were leaking a little bit, I applied this and it sealed it up with no problem. Only gave it 4 stars because I have not had a chance to put the boat in the water




Total Boat... Totally works


I bought a 1958 aluminum boat and was heartbroken the first time that I put her in the water. After receiving an email from JD regarding the tubes of TotalBoat sealer, I decided to give it a try. I used a wire brush attachment on my 4 1/2" angle grinder and completely cleaned the seams on the boat (I did NOT apply to any of the rivets). Then I applied the sealer in long, continuous beads along the seams. Unbelievable results! First try was 100% successful. It has been in the water for 3 days and the bilge is completely dry. Thank you JD for saving my project.

Works great


Followed the instructions to a tee. The reseal project went on without a hitch and a few days later hit the lake at Lucky Peak Dam near Boise, Idaho. Not a single drop coming into the boat. Great product and the salesperson's advise was spot on.

it is the best product


i tried several products to patch my aluminum boat. this one seems to stay on the best and is definitly the strongest. i would recommend this product this product over all the others that i tried. i did not use the mixing tip because of the amount of pressure it takes to push it through the tip. i just left the tip off and ejected the two materials onto some cardboard and mixed iit by hand with a stir stick then applied with a putty knife
