I purchased a very nice used dash pad for my 74 RR, it is the orginal black in color and it will stay black,I want to recolor it black, sense its a job to replace, I just don't know if it should be satin black, flat black or gloss black? I purchased duplicolor adhension promoter, and a can of duplicolor gloss black vinyl and fabric color. Can anyone inform me as to what color black that it should be??
