Hammer paint

The slightly iridescent areas are caused by the different orientation of very small shiny particles, which are suspended in the lacquer.

Mica is resilient, reflective, refractive, dielectric, chemically inert, insulating, lightweight, and hydrophilic.

To make the "hammered" effect more pronounced, a small amount of silicone oil may be added directly before application.

[citation needed] Hammer paint is often used to beautify technical apparatus or as a protective coating.

To get a regular paint to look smooth, the surface would have to be prepared first, for example, by spackling, sanding, grinding or polishing.
