That right stuff works like a mofo. It doesn't come off your hands either.
***** part was, got 7 of the nuts back on the sump, and the 8th stud broke clean off LOL, So I had to take it back off, clean off the impossible right stuff, and by the grace of God, my friend had the right size bolt, I found a nut, and I made a new stud. It's sealed up good now.
