K-LINE MATT DULLING SPRAY. The original favourite, for cutting flare on polished articles, now improved. Almost transparent, it can be used in colour photography without obscuring decorative designs. It is safe with most plastics. Used by museums on antiques, and in dentistry to reduce flare on polished instruments! Removes glaring highlights from polished surfaces in camera work. Coats evenly with a very fine spray pattern – it effectively dulls any polished object to be photographed.
