Paint & Polish
When it comes to painting, the surface has to be smooth and not uneven. An uneven surface indicates imperfections in the structure and thus would not enable the paint to make it look better or even hide the imperfection(s). Polishing is the process of rubbing a surface to make it smooth and shiny.
Polishing is done by using a special machine called the buffer. This machine has two wheels that rotate at different speeds. The buffing motion is used to polish the surface and remove any imperfections from it. The machine is powered by electricity and can be adjusted according to your needs.
