Digital BW, The Print

Hi Paul,

Other than the toughness and tackiness differences, did you (or anyone else) find 
much difference in the appearance of the coating (surface reflection, thickness, 
surface texture, overall "plastic" look, etc) and the appearance in the print through 
the coating (Dmax, etc) between Hydrocote and Liquitex coatings?  Thanks,
