4.0 out of 5 stars Great to repair leaks on metal fuel tanks, but you have to work quickly and use proper gloves
Reviewed in the United States on 12 January 2020
Worked great fixing the leak on my 50cc scooter's fuel tank. I deducted one star because after mixing the two components you have only about 2 minutes to spread the paste before it hardens. Also, the paste gets so hot that you cannot handle it with thin nitrite gloves and will need thicker gloves and wooden spatulas. Before starting the repair, make sure that you have the surface prepped and cleaned and all the needed supplies ready, because you will have a very short window of time once you mix the two components.

In any case, it covered the hairline crack in the tank very well and completely stopped the leak. After curing overnight, the repaired area was as hard as rock. I hope this review helps you with your buying decision.
