Digital BW, The Print

Obviously longevity and integrity  of the print will be paramount
when 
deciding whether to coat your prints or not. Print coating is a
contentious issue 
that has attracted lots of debate with no clear resolution far as I
can tell. There 
are complex chemistry issues involved with variables changing every
time a 
new ink set or paper is introduced. Is anyone testing hydrocoat for
longevity? 
Is it generally believed to be inert? Is a coated print stable enough
to mount 
with out glass? Has anyone tried it on a 9600/7600/2200 color print? 

Thanks,

Daniel
