J-B Weld 8217 TankWeld Gas Tank Repair - 1 oz.,Dark Grey

Worked well and easy. I just mashed what I needed between my fingers and thumb or rolled it between my hands. The even color tells you it's done mixing. It sets up fast. Only time will tell if it stops the leak in the tank. It has initially.

This stuff works. Sealed up a leak at my gas tank sensor. I am replacing the sensor. But, this works like magic. Excellent product

Had a dent in my motorcycle tank. Instead of pulling the dentni used this putty to fill it. It worked very well. Once I shaped it and painted it you couldn't even tell there was a dent. Good stuff. Will buy again if I need it

After doing lots of research I bought this item about two years ago, only after someone drilled a hole in my fuel tank and stole my gasoline. This item was easy to use, you just grab it and mix it by hand. I would recommend using gloves, and before you place it in place make sure you scuff up the fuel tank to help it bond better. the last one I used lasted two years then fell apart finally, so I just ordered another one and re-patched up the hole. it should last me a while, and it's better than replacing the whole fuel tank.note: the reason for 4 stars vs. 5 is that the first one I bought started to cure way faster and I had to rush to patch the hole. The second one I bought was a lot easier to mix and did not harden that fast but whiting 30 min of applying it, it was hardened and ready to go.

Worked great to patch a small leak on my 8n Ford tractor metal tank.

it works good

Purchased it to fix out RV fuel tank if a criminal steals our fuel.Hopefully it works when we need it.

Fixed motorcycle tank leak. Has survived over 9 months of abuse without fail. Withstands large temperature variations. Highly recommend following instructions on package.
