The paint itself probably works well if it's conductive - it's just a simple Faraday shield. The problem is with testing. For example most Faraday pouches and bags turn out to be snake oil upon testing, as they let the signal out through some discontinuities, even though the mesh itself works perfectly and most of the time you don't have the signal.
