- I am glad to find a solution to stop the leak in my aluminum boat! Now I can spend all day on the lake and not have to worry about any water coming in.

I had a seam like that leaking. I took the time to pry open the seam a bit, and cleaned it thoroughly with alcohol. Then took a Marine Adhesive and Sealant and I mushed it into the open seam as thoroughly as possible, then I hammered the seam back closed, and wiped everything clean. It's been 11 years now, still dry as a bone!
JB water weld is awesome stuff!
Someone replaced most all of the factory rivets that penetrated the hull for the floor stiffeners with SST nuts and bolts using bathroom caulk for sealant. Well, it leaked badly!
I took off the hardware, cleaned everything, hit the hull penetration with some light heat then, reassembled it all with a 1/16 think slice of water weld mixed up and placed under the washer. Also added some more on the top of the washer.
Then used Rustoleum Gloss Black oil paint on the water side of the hull. That was 10 years ago. Watertight baby!
Let the fishing commence! 😃
Awesome repair story!! Glad to hear it is still holding up 💪 I hope you are catching big ones out of that boat
Great job! I have used Flex Seal on a few different aluminum boats with excellent results. I used one of those cheap "chip" paint brushes to "paint it on" over all the seams and rivets. I do all the rivets on outside of boat and inside. Take your time on the inside especially if you plan on putting a floor in. Always great results. Enjoy the outdoors young man!
Thank you! And yes I do plan to use some more on my floor as I plan to put a fishing platform in.
Good job ! Flex Seal is amazing stuff, I have used it on a leaky boat myself. Easy to apply and it works !
It's the worse crap I've ever used. It peeled right off and will no hold submerged in water.
I would wire brush clean and spray brake clean in the seams before you apply any sort of sealant just a suggestion 👍
Best stuff on the market I used it on my aluminum boat and it works💪🏽💪🏽👍🏾
Great to hear you have also had success!! The cheesy infomercials were on to something
I just bought 2 cans of clear spray on flex seal!!! Hope it will work on my aluminum boat that leaks.. I'm going to seal the whole bottom of the boat, I think its leaking throw a few Rivets.. thank you for your time, and testing.👍
Awesome, goodluck and happy boating!
I have used flex seal spray on a couple of aluminum boats. It works great. I just paint the inside of the boat below the waterline. It looks great too.
I will try it on a plastic gas tank & see what happens in 3 days. Great video 👍
You need to use JB Weld Marine two part adhesive. Clean the area good and apply the JB Weld, it will set up and you can drill and tap it...very strong and waterproof
Jb weld marine didn't stick well to the aluminum for me, surface was roughed up to clean aluminum then used a paint prep cleaner. I used goop brand marine sealer/adhesive and it has held out really well, sticks good and has some flex so it doesn't crack or pop off when aluminum flexes.
Also 3m 5200 marine sealant works good
If it's simple and works, it ain't stupid. I did something similar with my 63 HaberCraft 9 ft, I used a can of TremClad paint. Sealed the leakes and showed my where they used to be.
Nice job bud
Glad the flexseal worked for your application. As some other people pointed out, you used the wrong jb weld. Go with the marine weld for your application, it’s rated to be submerged under water and for water applications. Hell, even the jb waterweld would have worked. But the marine weld is spreadable and more like a glue or paste, similar to the flexseal consistency
Yes thank you, at the time I did not realize there were so many jb options 😅
3M 5200 Marine sealant is likely the best option
Would jb marine weld work on a small boat like a pond prowler?
You used the wrong jbweld. Should used jbwaterweld. You could have used it to seal the leak while you where in the boat and it was leaking.
If I get another leak I’ll try to get some of that! Right now I’m still impressed by the flex seal.
Right on, man. Thank you!
Heck yeah, Flex it!!!
The front with JB is sealed? You only talked about the stern. And it seems as though it was in an area of the stern you didn’t seal
Did you measure the crack gap size? One just looks way bigger than 15 mil: that's the max that the specific JB weld product you're using is rated for ...
Seeing as how you have the boat out of the water and under cover, why no prep of the cracks? SOP is to DP, then drill a crack-termination at each end, prep for selected repair treatment. I've used Flex-Seal and it is reliable if the prep instructions are followed ...
Thank you for the advise!
Why was the surface not cleaned first, say with a rotary wire brush put into a electric drill or so?
Using Flex Seal to totally coat the underside of my 14 ft. old, leaky Jon boat. Using a paint brush to apply it, I’m expecting it will seal it all up nicely. Thanks for the video!
Awesome, that should work great!
Thanks for the information. Got a leaky 10 ft jon boat myself that my uncle gave me. Is it still holding up well today?
Yes it held up great all summer and fall! I went out on it about 2 times a week and never had any issues. I have not been on it yet this spring as the lake is still frozen :( but I have it sitting outside in the snow so surviving that will be the ultimate test.
@@diooutdoors Great to hear
Tanner - did you flex seal your jon boat? How's it holding up?
Try using a cheap 1 inch paint brush next time worked for me😊
Thanks for the advice!
i leave my jon boat in the water about 8 months a year. has anybody tried flex seal under similer conditions?
Hey I know this was posted awhile back but I’m desperate, I bought a very similar aluminum boat and I can’t find a drain plug that fits. Looks like what you have there is exactly what I’m looking for, where did you get it??
I’m really sorry but the drain plug was already with the boat when I bought it… I wish I could help. Maybe look up your model on alumicraft website and they may spec it…?
@@diooutdoors it’s cool, thank you for the reply. I’m waiting to hear back from alumicraft. I’m about ready to just bring it to a shop and pay them to put in a new drain plug system that would work with a standard 1 inch plug lol
Just get a metal screw in plug from Home Depot wrap the treads with teflon tape and put flex seat on both sides. Bam! Done.
Ngl I was thinking about just coating an aluminum boat with flex a seal inside and out, call it done 😆
That boat would never leak 🤷🏻♂️
Distribuidor en MEXICO? Gracias
I’m curious how long flexseal will last. Can you comment or some thing how long in years the boat didn’t leak?😅
So far: 1 year :) and it sat outside in the snow all winter.
I've used it on stock watering tanks and am somewhat not impressed. Marine JB Weld epoxy is much better, IMO.
10 years, and still not leaking.
Wtf. Try cleaning the area where jb weld goes. Get marine jb weld or jb kwik weld.
The split at the front was filled with jb then gone over with flex seal. Flex seal would not fix a split that wide.
If you used the right kind, and actually used a reasonable amount, that boat would have outlived you.
Is it paintable??
I am not sure about that, I have not tried to paint over it.
If your asking to use a paintbrush to apply you could probably do so
For about a week
Whatever floats your boat pal
This is the best comment I’ve seen 😂
@@diooutdoors thank you thank you I try😂😂
i would have used 3M 5200 you put that on and nothing is getting into the boat...and you'll never be able to take it off lol
Bro got a leak in his smile too 😂
Hey now, that was uncalled for
Always that one guy
That guy is a dick head … nice job on your video.
It's the worse crap I've ever used. It peeled right off and will no hold submerged in water.
Gluvit say work
THATS ALOTTA DAMAGE!
Horrible comparison
You will have more invested in jenky repairs than the boat is worth to begin with
It happens. Sometimes it’s the sentimental value of the boat that the value is in.
