Reflective paint for metal is a special coating that reflects light. It contains small reflective beads—often made of glass or similar materials. These beads catch and bounce light back toward their source.

This paint is usually applied in thin layers over a primed metal surface. When light hits the painted surface, the embedded beads scatter the light and reflect it. The effect is especially strong at night or in dim areas.

PVD stands for Physical Vapor Deposition. It is a vacuum-based coating process. A solid metal turns into vapor. Then, this vapor settles on the surface of the part and forms a thin, strong layer. This layer protects the surface from wear, heat, and corrosion. PVD does not involve liquid chemicals. It relies on high heat and vacuum technology.

Black oxide finish, or blackening or oxidizing, is a chemical conversion coating primarily applied to ferrous metals. The process involves treating the metal with an alkaline solution containing oxidizing salts, which reacts with the surface to create a thin layer of black iron oxide (Fe3O4).
