ProSeal Instant Gas Tank & Radiator Repair, 1 oz – Steel-Reinforced Epoxy Putty, Permanently Seals Small Holes, Cracks & Split Seams, Adheres to Wet Surfaces

I've been dealing with a crack near the bottom of my fuel tank on my 79 Jeep J10 for a long time. I took the fuel down low so the crack would be dry. I cleaned it up with sandpaper and made sure it was dry. At first I thought this product was tough to knead, as it was but it's worth it. At first it seems like it's not bonding but over maybe 1 minute I could tell it was getting stickier and stickier. I got it where I needed it to be and wow was it clearly adhering. Not one drop has leaked through after setting. This is what I'll always use from now on. It shut down a full big crack completely. It is rock solid. Huge fan.

This putty is the best. I fixed a fuel tank leak. 2 hole I've repaired. Im widowed and have to do things on my own. It really works. Follow the instructions to the T.

I was concerned at first because the leak wouldn't stop. The gas tank empty is the best time to apply. Will work with a leak but will take longer. If the hole is less than an inch in diameter, should work. Irregular damaged, like exhaust burn works too.

Worked great for 10 months

It says that you can apply to wet will instantly seal leak Etc. Does not work does not seal the leak and does not stick. Complete waste of money and waste of time. If you do not clean the area perfectly probably will not work and may not even work then. Total crap don't buy

It has been a month or so since I purchased. To begin with it seemed to uphold, as described and I was impressed with the hardness and that the leakage stopped. For the price it seemed good for the money. Then the cold temperature hit and it and the durability weakened. It actually fell off. I would say good for spring and summer but not if you live somewhere that gets cold weather.

Excellent product

I had this on hand when I got a gas tank puncture on some road waste—Gasoline was leaking in a steady drizzle through a pea-sized hole under the back of my car. I mixed the putty as instructed, and pressed it firmly against and into the hole. Not only did the gasoline immediately stop spewing, but as advertised the patch was rock solid after just two hours. This is a permanent fix that has now held up fir several months without needing to apply another layer.

good for small jobs

This stuff really works. Fixed my gas tank within minutes. Fast and easy. .

So far so good

Preparation is the key with this product. I removed the tank and drained all the petrol out of it. The area was cleaned with a wire brush (gently) and the product applied as per the instructions. I left it to cure overnight before refitting the tank and filling with petrol. No leaks so far. Pretty good for the money
