There's no such thing as permenant fix in a bottle. These products have Sodium Silicate in them, which if that word may ring a bell, was the product used to seize the engines in the cash for clunkers deal. So think of it this way, as your waiting for this stuff to seal, it's bypassing the bad head gasket, gettting into your engine, in bearings, in pumps, and tight tolerances.....it may temporarily fix it, but in the long run, youll be replacing more then just the head gasket. If it doesnt seal the head gasket at all, now ALL of the sodium silicate is in the engine, which sounds like a couple of the stories above this post.

My .02, send your buddy on a wild goose chase for a day while you fix it like a real human being with at least both lobes of your brain lol.
