This story excerpt and quote from astronaut Stephen Robinson while working with the experimental tile "repair kit" in the shuttle bay caught my eye: "''It's about like pizza dough, like licorice-flavored pizza dough,'' Robinson said as the near-black filler material oozed from his high-tech caulking gun. He used a putty knife to smooth down the substance, again and again." I use a black filler material in my job, high-heat rated, applied with a putty knife- and the stuff smells just like black licorice! I haven't tasted it yet, but then I'm not an astronaut... ;) I bet he's using the same material that I do, or a variation of it. ____________________________________________________ Start your day with Yahoo! - make it your home page http://www.yahoo.com/r/hs
