Kevin,

       I bought a bottle of this in order to keep driving my van while I
     acquired enough parts to fix the terminal head leak.  The instructions
     on the bottle say to drain and flush the cooling system, refill with
     water and Moroso sealant, run at temperature for 10 minutes, then
     drain system and leave set overnight until ceramic has set up.
       Well, I decided not to use the stuff because that was way to much
     filling and draining of the system.  Plus I had concerns about coating
     things I did not want coated like the hoses and radiator.  I did use
     the Alumaseal (two tubes) that did NOT do a thing to stop the leak.
       I drained and flushed the system (using a flushing tee, much easier)
     and now I just add water.  I can drive 50 miles on a quart of water.
     Hopefully, my AVP engine will arrive this week.  So, if you are
     interested in a bottle of the Moroso sealer, let me know; maybe I can
     send you the one I did not use.

     Vince.

     Subject: Moroso opinions sought

     Someone on the list recently recommended Moroso ceramic cooling system
     leak
     fluid. Does it work? How do you use it? Do you have to drain the
     system and
     fill with water? How much do you use? Can it do damage? Are there
     other
     products easier to use which are just as effective? Better?
     The situation is this: Coolant disappearing from the overflow tank,
     and no
     visible external leaks. Some visible white steamy exhaust on startup.
     Thanks for any guidance.
