I had forgotten that I had used J-B Weld to repair a water pump on a 1976 Jeep Wagoneer that I had. Living in Ca. on the economy as there was no base housing available at the time so money was tight. Found a water leak in my Wagoneer at the water pump. No money for a replacement. 1stSgt. suggested J-B Weld. Removed the water pump and found there was a lot of corrosion in the housing. Coated it on every surface that I could. Let it harden for 24 hours (actually about 36) and put it back on. Drove it another two years and it was still holding when I sold it.
