He sure was. We saw this version of it a couple of years ago [ http://www.youtube.com/watch?v=TD1LHejil6M&feature=related ]. In this one, the presenter almost cracks a couple of times, but the boffin in the white coat is rock solid.

It really depends on what method you used to mask. Liquid mask, tape, rubber boots, etc. It is something most learned thru trial and error, much like running the parylene machine. It's never as easy as loading it up, turn it on and watch it go!
