Magnetic paint and magnets
Choosing magnetic paint: You can buy magnetic paint in many stores, but remember that price and quality are usually related. And thereby cheap magnetic paint often becomes more expensive than the high quality paint.
Explanation on why cheap is more expensive: you have to paint several layers of the cheap magnetic paint to get an OK result (5-7 layers), which requires much more paint than if you had chosen the good quality one from the beginning. And each layer has to dry for 12 hours, so it also takes unimaginably much longer to paint with the cheap version. And the result is often sharper with high-quality paint than the cheap one. The reason is, among other things, that there are more and better magnetic chips in the "expensive" paint can than in the cheap one. And in the end, it can be really expensive in magnet purchases because ordinary fridge magnets rarely stick to a surface painted with a poor quality product.
