* What Whiteypaint does to look decent on slightly textured painted walls (I haven't used other whiteboard paint, but I've used stick-on whiteboard sheets and had the same problem: bumpy wall, whiteboard marker, ugly drawing).
* Why Whiteypaint is especially easy to clean.
* How I'd go about un-Whiteypainting the wall if I was dissatisfied with it.
(I'm not going to argue with anything of your answers, if they're answers. I'm seriously interested. I know exactly what wall I'd put it on.)
The cost of a bucket of expensive paint is a rounding error to me, and, to be honest, so is the cost of having someone clean up a wall, but the wall cleanup also comes with a lot of logistical headaches for me.
