I thought about using magnetic paint for quite a while. So I just bought a bottle of it and started painting. I used three layers of the magnetic paint (you need at least two ones, so that magnets will hold) and after that one layer of normal grey colour. I decided to paint over the magnetic paint, because it has iron particles in it and so the resulting colour is not that evenly distributed. I am very happy with the result. It looks great, is somehow geekish, it’a functioning really good and it’s totally useful for me (will use it for to-do and shopping lists). The magnetic paint is a bit more expensive than normal paint (about 50-60€ for a wall of 2 m^2 with two layers of paint). So yes, all in all I can really recommend the magnetic paint.
