In this work the mechanism of resonance is proposed as the way for determining of paint age, by application new method. This new method consists in accelerated growing old of paint on the basis of resonance. Measuring is concerned with humidity of paint and it is a general method since water molecules are present in every material. Besides, the water molecules are dipoles so that the resonance with them can be achieved and by the mechanical/electrical way. The molecules of water have random distribution. They oscillate in shallow potential wells so that they can be ejected from paint with low energy quanta. It is the reason for decrease of paint humidity by evaporation process. The high energy quanta accelerate the process of ejecting water molecules from the paint. On the basis of this, it becomes obvious that the increase of energy of water molecules accelerates the growing old of paint. Since water molecule is mechanical oscillator it can be translated to resonant state by application of mechanical periodical field but also, since it is dipole, it can be translated into resonant state with periodical electrical field.
