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

good for small jobs

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 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
