Fujiflex. Don't worry about my trimmer technique - I've used it for a long time for Cibachrome, which
is even more fussy and very easily scratched or dented. But you are correct pointing out the risk of that little bar cover on the Rotatrim - it will be removed for roll work in the dark, and substituted with something more appropriate. Per dust - I try to work very clean. It was almost impossible to
retouch Ciba, so had to get real good at this. And even Fuji polyester base will show any kind of
opaque color as a zit on that high gloss, though you can use penetrating retouch dyes to build up
a minor white spot caused by dust. The nice thing about the Fuji is that it isn't highly electrostatic
like the Ciba base was (virtually a dust magnet!).
