This paper presents the results of experimental tests on coating systems for military applications. The evaluation of properties is performed based on measurements of thickness, gloss, hardness, and surface roughness. The spectral characteristics of the tested systems and color parameters are presented. The tests are conducted for two-layer masking coating systems made in three variants: coating system (SP1), coating system modified with carbon nanotubes (SP2), and coating system modified with glass microspheres (SP3). Analysis of the obtained results reveals that these coating systems exhibit similar thickness, gloss, and spectral characteristics. The SP2 system is characterized by lower hardness, while the SP2 and SP3 systems have higher roughness.
