hello all

   i have used Ronnie Graves PRS Duralimb Resin and Pigment for several
years. they offer 1-18 pigment shades. We still use the Otto Bock color
swatches. If using Duralimb or a clear resin with the PRS pigment it may be
necessary to drop down two shades when laminating. For example if a
technician recieved a completed measurement form stating the shade of otto
bock coloring swatch number was 15 it would be neccessary to use the number
13 PRS Pigment.

hope this helps
