Did you make it yourself with the same whiteboard repair fluid that the author used? That seems to be the key, though I've never tried nor seen the product.
I've used glass over (x), but it's heavy and expensive in large sizes.
The cheapest portable whiteboard option is the laminated MDF sheets they sell at Lowes. $15 for a 4x8 foot sheet.
The whiteboard paint is merely OK...it's difficult to erase, unless your wall is glass smooth.
Chalkboards are beautiful but create way too much dust for use near computers.
Rackspace grew up on the laminated MDF sheets. They are not easy to erase, either, especially if the marker has set in. The top coat and the markers used really matter.
Yes, that's true. The brand of marker, and even the color of marker makes a big difference. Expo blue and green seem safest, with red distinctly unsafe. And burn in is real, though you can often get stuff clean with a decent vinegar based solution...but who wants to do that?
That's why the whiteboard repair fluid stuff sounds interesting. The only good options I've found for eraseability are a good expensive whiteboard (and even then you takes your chances) or glass (which you can paint the flip side of or put over wood, etc for aesthetics -- but it gets heavy and expensive, and I guess sort of dangerous, at large sizes).
