My buddy has a 98 trans AM with 120K brutally hard miles. His rear main started leaking and got progressively worse. This is not a show car by any stretch. He dumped some of the blue devil rear seal sealer in and incredibly after 2 days the leaks is gone. He estimated it was leaking about an ounce a week. Bottle says its a permanent fix, we shall see. So far 400 miles and dry as a bone.
