TankWeld Metal Fuel Tank Repair Kit

Stopped the leak in my gas tank, but it started to leak again after I went through the car wash a few months later but a good temporary fix if you need to get your car back on the road and save up enough money to get it fixed professionally

This stuff fixed my mower

This product helped save a 30-year-old gas tank on a log splitter. Have everything ready and sanded and cleaned and ready to go. Once you mix this epoxy up it will get hard in just a couple of minutes. Wear gloves! The pack age gets extremely hot and will flow out perfectly and will harden right up and be able to use the part in no time. Do not think you have all the time in the world to work with this product. it will harden almost immediately and will get extremely hot in your hands! Hands down a great product and will save some really expensive parts that can't be replaced easily.

Great product but not for my application. I was using this for a home heating oil tank with a slow drip. It does not bind well to a wet surface, let alone one covered in diesel. That was mainly my fault though since I should have drained it but I still had about 100 gallons left in it so the static pressure was pushing its way through the liquid JB weld and not sealing. If you're in the same predicament, I suggest their Water Weld with the blue label. Worked first try. And dont let the reviews fool you, if you mix it properly it does not set in seconds. Not sure what they're doing wrong.

This seems to be a very tough tank weld and it fixed the leak that I had (which I will describe further on), BUT, the most important takeaway from my review is DO NOT FOLLOW THE INSTRUCTIONS!!! Because if you do, you will end up with an unbearably hot, rock hard bag of glue! The glue will start curing by the time you finish mixing it in the bag! It is EXTREMELY important to first empty the black compound, and then empty the white compound beside it. I would recommend doing this on a party paper plate. And when everything is ready, start mixing the two compounds together with an 1 inch wide wood shim. If you do it my way the glue will cure in approx 8-10 min from the time you start mixing, vs approx 3 min from the time you start mixing if you mix it in the bag like the directions tell you. I know because I tried it both ways. I used it to fix a large rusted and pitted area or a John Deere 2640 gas tank, and the fix seems to be incredibly sturdy! I hope this helps somebody! God bless

Mixed feelings about this one. I’ve used JB Weld for years, but, only tried to apply it where I thought the product would function best. I had a crack in a fuel tank. I was able to clean everything off of it, while in the car, and with the help of a electric solder iron did the repair. It was difficult to get it 100%, still a slight bit of sweating. When the tank was completely dry and completely clean, I applied the JB will patch kit. it was a difficult process!! Laying on my back, applying this upwards, trying to get the cloth and the Epoxy in the right position. I wasn’t really happy with the job. However, the leak went away. For about four months the Repair seem to be good. As I feared, the leak came back. I removed the old JB Weld, which didn’t seem to have very much adhesion , it came off in one big clump. Re-solder the area, this time with the gas tank cap off so there was no pressure, and reapplied a new JB Weld tank repair kit. This time, I did not use their nylon material, I used metal screening, and, I mix the epoxy in four different batches, it is much easier to work with and you’re able to layer it in a much more efficient manner. As of now, as before, the patch is holding. We’ll just have to see where it goes in the future. I’ll continue to use JB Weld products, as always, the preparation of the site, and how it’s applied is pivotal whether or not this cold patch works effectively. If the leak continues to return, I’ll post that in the future. *** UPDATE*** 06/24/25 It failed again!! Same as described above!! Damn!! Lasted about 2-3 weeks then a very small drip. Parked the Geo. I tore it down and exactly as before. No adhesion!! The patch just popped off with a screw driver. So, I’m done with quick fixes I Ordered a Dorman tank replacement and will r/r it when it gets here. Very disappointed!! Again. I’ve used JB weld with better results. Not this time X2!!

I've used this on two gas tanks that have had small pin holes that leaked. Both tanks have successfully been sealed without failure.

Good

Produto excelente! Precisa seguir as orientações do manual e usar bem rápido, porque ele esquenta muito.

Arrived in good order and a good product for what I have used it for.

Worked great on the gas tank for my Farmall super MD

La tela es difícil de cortar o seccionar por la forma de los hilos. Es súper importante respetar las porciones porque aunque quede un poco más del componente b, después no seca la mezcla

But must use in one minute otherwise dried and must use hand gloves otherwise will start burning Bcz of chemicals heat
