1960 Chevy Impala gas tank

If the holes are small, you can buy a 2 part gas tank repair clay. You just mix it together and it hardens like steel. It works really good too. Just make sure to clean the surface of the area your repairing. Use a good wire brush or a wire wheel on a drill. Ive used it before and its a permenant fix. Its really cheap also. Any of your local auto parts stores should carry it. It says gas tank repair right on it and it comes in a cylinder shaped tube. Good luck! :)
