I'll assume you mean "matte paint", in which case it is simply a paint which isn't reflective and has no sheen (ie. it isn't shiny) to it.
At home this can be achieved with a piece of abrasive material, a bit like a pan scrubber! In the workshop we use a "scratch brush". In much the same way as a highly polished piece look dull after the scratches of day-to-day wear and tear, then a dull finish will eventually wear shiny. The dull finish, just like the highly polished finish, can easily be restored by your jewellery workshop.
There are many ways, sand-blasting, very fine sandpaper, (400 to 600 grit) for contoured plastic, a fine sandpaper flop wheel. (to name a few)

When a piece of sodium metal is cut, it is exposed to air, which contains moisture and oxygen. This leads to the formation of sodium oxide and sodium hydroxide on the surface of the metal, which gives it a dull appearance. The shiny surface of the sodium metal reacts with the surrounding air and moisture, forming these compounds which are not shiny.
Sn is a shiny, silver-white metal. It exhibits a metallic luster and reflects light.
