I don't like the sound of this stuff, I can see it clogging the system. If anything then only a ginger root based product like bars leak tabs (GM tabs) or Holts (also Subaru labeled).
Ginger root has the unique property of expanding in the prescience of air once its been soaked. It flows though the system as harmless fine particles until it finds a leak, it then expands in only that location to seal it. I have never known it to clog any system, GM and Subaru and possibly others have used it in new cars from the factory.
