Does dry erase whiteboard paint work?

More coats the better, it makes it more smooth, and earses a lot better, also I had to cover BRIGHT pink. So i ended up painting 4 coats. Before that i only did 3 and it would not erase very well so i did one more coat. The people who make the paint told me to wait about 2-4 days for it to dry, also do NOT use low odor expo markers. sooo ya if you do it right it wil be good. It works really good for me!
