Anyone eve used Lucas Power Steering fluid leak stop?

 

Any ps fluid leak should be repairable with the correct o-ring. Is it the Saginaw series?

 

I would rebuild before I used any kind of "leak sealant" I like Lucas products but I know that for around $10 you can buy any kind of power steering pump or power steering rack rebuild seal kit! try this site and see if they have what you need.
