Hi, Group!
Wait-Wait-WAAAAIT! Hold on a moment! "Just get it on your skin or breath [sic]
the vapors!" WWHAT!? I believe that you might have wanted to say, "Just DON'T
get it on your skin or BREATHE the vapors!", right? MEK, MethYL-Ethyl-Ketone,
is VERY volatile, and absorbs easily through the skin, so these were
well-intentioned words of warning - They just didn't quite come out right.
And thank you for the information - the cautionary note is greatly appreciated!
Dave Garfield, who probably doesn't want to go near MEK after all that... ;->

MEK stands for Meth-Ethyl-Ketone, and yes, I have seen something like an order
of magnitude difference in how much of the green foil leaves the traces, and
does not get re-deposited on the bare fiberglass elsewhere.
Available from McMaster-Carr

http://www.sciencelab.com/msds.php?msdsId=9927358it is not expensive, $10 for a quart. Just get it on your skin or breath the
vapors!
