went through a similar scenario years ago, Had a pro welder try to weld a hairline. After hours of attempts we never got it sealed. Naturally we cleaned it several times before hand. Tried jb over the welds- nope. For the additives some swear they will partially clog up radiator & other components. It has to go somewhere right? In the end drove it till it died & a buddy bought it & dropped in a diesel.
