Re: Simplest coating system possible?

It might be worth a call to the University of Hawaii¡¯s thin film lab - . If nothing else a chance to tour and look at the equipment will give you a better feel for what you¡¯re up against. You might get lucky and run into a fellow enthusiast¡ ? David A. Grove Senior Research Engineer Luxel Corp. ? A good politician is like a good football coach. He has to be smart enough to do a good job but dumb enough to think it matters. ?

Subject: RE: [VacuumX] Re: Simplest coating system possible?? ? Right now I think that my calculations put me someplace
between $20,000 and $50,000. I don¡¯t think many people
are going to be prepared to share a meaningful percentage
of that investment.
