OK you Phil Swift fans,anybody here use this stuff? I am the type, believe half of what you hear and see, Anybody have any experiences with this?

I ask cause for months I have put off a very slow drip on a elbow cast iron drain pipe, in the corner of my basement by the floor drain.I can fix this much cheaper than a plumber. Well I'm still down but when I get out I can supervise my grandson or III on how to do it while present with on of them.

Anybody think of something that will work for a month or maybe longer?
