Hi Bruce,
I prefer the matte look... but sometimes glossy looks better. Depends on the image.
I use acrylic mediums. Quick, easy, no fuss, no muss.
For papers, I use Stonehenge. For the past few months I've been using Arches Platine, only because I got a pack of that bad batch. No good for kallitypes but working very well for carbon. Better than Stonehenge, actually, due to it being a much heavier paper. I've got some "good" Arches Platine, that I've been using for carbon over kallitype. Very happy with the results.
Sometimes I print on Ilford Matte Fibre. Beautiful paper which shows off the relief... slightly more than matte acrylic sized papers. I just have issues with wasting all that silver, though...
