What Does Pinhole Mean?

A pinhole is a pore-like penetration that is present in paints and coatings due to the entrapment of moisture, air, solvents or other fluids. The presence of pinholes increases the corrosion rate experienced on a surface due to the moisture pockets that cause crevice corrosion, pitting and increased redox reactions.
