The Tool Welder were I work swears by MISON gas , I don't know It's

the guy commonly performs miracles with the stuff. He say's with MISON

he could weld the production managers lips to the general managers butt (
as long as they hold
still long enough, wich shouldn't be a problem ).
You might be able to find something about this gas on the net.
