Best product to repair pin hole in hot water tank?

Don't even bother,if you repair it another hole will pop up very soon,the tank is rotten(unless you punctured it)it has passed it's useful life and is now scrap.The more you repair it the more stress you put on the rest of it ,then more goes,flogging a dead horse.Sorry but I don't want you to go to expense on a bodge that wont last 5 mins.Good luck.x
