As per historic assumptions, a painting art that is approx 5000 years old, the ancient Egyptian civilization gave shape to an extremely symbolic and fascinating era of paintings and sculptures that mesmerize people to this day. In prehistoric era, paints might have been prepared with natural gums, natural resins, plant-extracts, egg-extracts, animal's fat etc as binder whereas grinded rock powder & minerals as pigment and water had been as a common solvent. Paint preparations have been improved gradually as per developments of civilization by applying innovative techniques and technology to get superior quality of paints and surface coatings. Systematic study has made known that contemporary paints are being formulated to encompass shape from amorphous to crystalline, from micron size to nano size, configuration, dispersion stability, film smoothness, better aesthetic looks, required enhanced quality and forcefulness to both exterior and interior paintings of industrial automobiles by applications and blend of appropriate ingredients i.e., resin, solvents, additives and pigment. In progressive circumstances, paint technology presents an extensive and wide range of methods and technologies that design and make advances in the exterior as well as interior properties and characteristics of materials and components by the way of alteration, arrangement and coatings for the purpose of protection and decoration. Functions of the surface coatings technology have been extremely widespread i.e., from micro to nano technology and from extremely hard materials to soft polymeric coating materials. Recent novel applications of nano-materials in paint-formulations promise to carry out the requirement and fulfillment of automotive glossy as well as protective surfaces; calculated as 90-94%, enhanced adhesion; i.e. 100%, weathering resistance; (408-1416 hours passed in quick ultraviolet accelerated weathering resistance test), corrosion protection; (600-2400 hours passed in salt spray test) and get enhanced mechanical properties. Self-cleaning properties of painted surfaces have been attained for better protection by applying nano materials.
