Anti-newton glass substitute
I read some where a long time ago that you can substitute anti-newton ring glass with normal glass sprayed with hair spray. Has anyone tried this? Could opitical perspex be used instead of glass in a negative carrier?

Norm, that hair spray thing just sounds like a really bad idea. First of all, it would never deposit on the glass in an even layer, but would land in droplets and would never be smooth and flat. Secondly, it probably isn't perfectly clear; as in optically clear. Third, it may well leave gummy residue on your precious negs. My wife uses it occasionally, and the bathroom window directly behind where she sprays it gets gummed up with big amber-coloured splatter droplets of the stuff.
It is handy in the workshop though, when you want a low-strength spray adhesive An old skier's trick when shortening a pair of ski poles, is to knock the grips off, cut the poles to length, and glue the grips back on with hairspray. Works great. As for acrylic, I'd worry about fine scratch marks from cleaning. It would be softer than glass. Otherwise, wouldn't its smooth surface also be susceptible to Newton rings?

If you're in an experimental mood, you might consider visiting your local framing shop and asking them to cut you a small piece of anti-reflective glass, also called "Art Glass". I tried it on my scanner as a way to get the negs flat, and it seemed to be very benign in that it did not optically degrade the image sharpness.
