Hello chemical guy. It sounds like after reading your posts you were looking for a cat fight or am i missing something. Thats what seems to be happening now. You could have spared me from having to read your posts and all the other additional followup if you had just said,"... I dont think he meant chemical reaction. What I think he meant was ...", and have been done with it. Thanks for the explanation of the nonchemical reaction. Are you really a chemical guy? If yu are you might be overqualified to be working on this bbs. I am sure you wouldn't like to be patronized if you were to switch places. Thanks again.
