Digital BW, The Print

Dear Group:
I believe that generally it's not advisable to drymount any type of
"fine art" pictures, but I really prefer to see the photos flat,
glossy, on a hard board, and not behind glass.  Thru
the years I have frequently drymounted traditional photo prints
(Ilford Galerie/Agfa Insignia) on matts or 1/8 of 1/4" Masonite. 
Someimtes I bond archival watercolor paper to the Masonite and then
mount the photo onto that.  Now I'm drymounting B&W prints (Epson
Ultrasmoothe Fine Arts paper) from my Epson 4800/K3 inks on 1/8"
masonite. I
print my pictures (usually 16 x 20") full frame from 8x10 negatives,
and the board is the same size as the picture.  I'm using a
Seal 210M press set at 200F and pressing the assembly for about 5
minutes.  I'm using some old Seal RC tissue for now.  I'm also
experimenting with different varnishes- I'm applying the varnish after
the print is mounted on the board.  Havn't really settled on any
brand or
product yet.  I'm kinda flying by the seat of my pants on all this. 
Is anyone else using Seal or any heat/pressure mounting
devices/tissues with inkjet papers?  I'm considering double layers of
drymount tissue.  Any input on best tissue brand,
pressing times/temperatures, technical resources, archival issues
would be appreciated.
 Thanks, Kip.
