Anyone use one? Seems like it would be a neat tool to have but the cost is too much for me. Hundreds to thousands of dollars isn't likely to happen. I read on a few sites Gloss meters measure the distinctness of image gloss. They can be as simple as a sheet of paper with a graduated scale of thin black lines that you hold up to the paint finish, or as complex as an expensive electronic viewing box.. I'm not sure what the papep is or exactly how it is used.
