I've been side-tracked from the wire-rod coating.  I do not coat everything.
I have a show that I'm preparing for and inksets that I'm trying to perfect.
For the show, most of the pieces are going to be traditional matte under
glass (acrylic).  With respect to the new inksets, I want to perfect the
matte printing before going the next step to coating.

A light fixative (three very light coats) is not a big deal to me.  It has
no effect on the image, but the pigs don't rub off easily.  I can easily do
this in my garage with no breathing or equipment.  There are aerosols that
are very archival and work fine.

I'm also interested in RC papers for a number of reasons -- easy dynamic
range, relatively tough surface, maybe even better pigment encapsulation if
coated.  If an Epson Archival pigment-based vm-s gives me 100+ years on an
RC with a 2.0 dmax with no coating or other work, a look that I like
(questionable), and a surface that doesn't get ruined with the slightest
touch, that may be hard for me to resist.

I'm fully into making the best looking B&W prints with the easiest process.
I'm trying several promising alternative approaches to get there.  I think
the gallery market will want truly archival matte paper under glass.  Lots
of people like the glossy or RC look.  I personally like matte, but I don't
like the sensitivity of the surface to damage, and I don't like glass --
which defeats a lot of the matte advantage.  An archival, matte RC with a
dmax of 2 and an abrasion-resistant surface might be a very interesting
product.  I doubt that it currently exists, but I think it could.
