|Halvor and All: I got some "Gampi" from Kinsella and I've had
|a very hard
|time with it. Just can't get a clean print. VERY hard to coat. It's
|brownish -- paper bag color, really -- and dries to a lovely
|old parchment
|look. But I can't get even coating. Image comes out mottled,
|uneven, etc.
|I used about as much pt/pd on it as I could bear, then put it
|aside. Would
|love a suggestion or two. -jb
