JB Weld....

The 03 Dakota that we picked up for Josh had an oil leak when parked facing down hill. I thought the front of the pan gasket was leaking. Turned out to be a rusted pin hole in the font of the pan. Yup - we parked it up hill, cleaned the area and JB'd that thing. Never even took the pan off. 2 years ago. Still holding.
Oh yeah definitely good for those type repairs etc.
