I wanted to put up a whiteboard to cover the entire 8x16 foot wall of my apartment living room. Ideally you'd use ceramic coated steal, but that's extremely expensive and heavy, so you'd like a cheaper alternative. The problem is that every other surface besides glass and ceramic seems to ghost, without fail. After researching every product and lead on the Internet I could find, my brother and I tested all of the most promising options: 1. Bare panelboard, the super cheap stuff you get at Home Depot. 2. Panelboard coated in gloss enamel. 3. Panelboard coated in some kind of sealer. 4. Panelboard coated in Rustoleum whiteboard paint. 5. Some disposable whiteboard squares. 6. Many others I've forgotten, including applying the foregoing coatings in different ways, e.g., painting, buffing, sanding after drying. In the end, we found the most economical and ghosting free alternative by far to be bare panelboard and Mr. Clean Magic Erasers. The erasers are magic indeed: They effortlessly clear the board and leave no ghosting. At first I was worried the panelboard would be damaged, but after significant use, we couldn't detect any. Still, perhaps at some point the panelboard will wear out; however at $12 for a 4x8 sheet, and with the ease of installation, it's well worth it.
