I've seen pictures of a racetrack made with magnetic paint on the wall. Like this:

I think its really cute and am tempted to make it but then I wondered about kids playing on it. If little kids drive cars along the wall is it going to look messed up--chipped paint, etc in no time? It would be for little kids, of course, so they can only be so gentle....
I've never used magnetic paint before? Any experience with it?
