Wendell -

There was a lengthy discussion gold foil screens last year. Check the archives.

If you can't find the postings in that mess of files, let me know. I aggregated
all of them thru October of last year into one searchable file (minus all the
extraneous stuff that gets added to a posted email on LML). I also saved some of
that thread. I can take a look in a week or so after I get back from a trip.

Cheers,

John
