Just one point for Clayton. The few prints I have done using BO and Eboni ink on Epson Premium Semi-gloss exhibited very little if any bronzing vs the same prints using QTR and hence introducing the LB, LM and LC inks (Epson 2100 with MIS Pigment Archival Colour CFS with Eboni in the MK slot). So waxing is likely to offer little benefit beyond the spray which is required as an adhesive to lock the Eboni to the RC paper.
