This is an ADD ON feature for all my wood products. There is an UPCHARGE for this special High Gloss Finish. The up charges are for EACH piece. So you must change the quantity when adding to cart. (i.e. 2 backplates, qty. 2) There is a slight discount if you purchase a complete set (2 backplates and truss rod) and that quantity remains at 1 as it is per set.
