Yes, as I said, I use a very, very small amount, and there is an
almost imperceptible slight sheen to it, but definitely not shiny-- at
all. I think it depends on how much you use. But, honestly, even to
see anything, I would have to tilt the print a certain way to see it
from the side. There are times when I've coated a sheet (I only coat
after the first layer is down)-- and I can't tell if I've done it or
not, so I have to hold it under a light and tilt it to see. Even
then, I have trouble making sure. So if you really use it sparingly,
you simply can't see any shiny effect at all-- at least not in mine.
Maybe it depends on the paper, too. ??
