Now, magnetic paint isn't all it is talked up to be and knowing what I know now, I wouldn't bother with it. It's difficult to work with, stinks to high heaven and you really need to use items that have large magnets on them. I would do the chalkboard again though.
I have one more door to do this weekend. Going to do glow in the dark paint on one side and a distressed gray on the other side. Can't wait to see how this one turns out!
