Amazon Customer 4 UPDATE: After a few weeks of use, it improved. Although it still looks strange (more of a matt finish than glossy), it is more normal to write on now, and the ghosting after erasing has reduced. Actually quite good - so I increased the rating up to 4 stars.Previous: It kind of did the job. The whiteboard looks weird now. It is dry, but not smooth and shiny. When writing on the board, the ink behaves a bit like water on oil. It does wipe clean easier than before, but it still takes a bit of effort, and there is still ghosting. Having spent over 5000 yen on this, for another 3000 yen I could have had a brand new board. I'm interested to see how long this coating lasts, and what a later resurfacing will be like, but after that, I suspect that in the future I will probably just buy new boards.
