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.  ??
