Furnace Cement is Great Stuff!

Hey Guys!

Remember some time ago I had an exhaust leak and tried the Furnace Cement?   
Today I pulled the old header on which I had smeared the stuff to seal the 
leak.  The stuff was hard and intact.  Someone asked me a couple of weeks ago 
about it and my answer was positive, but I had not been able to really 
inspect it till today when I pulled the header off and out.  Good cheap stuff 
to have on the shelf.
