Has anyone used Lucas power steering stop leak? My 69 RR pitman shaft seal leaks and I was thinking of using this Lucas product. I loose roughly 2 oz a year from the seal. Any advice.

Yes,.....I've used the Lucas power steering sealer,....it's about the only product Lucas makes that really works!.......small leaks, or seepage leaks,....anything else, best to replace or rebuild the unit in question
