2. Brasso - Wikipedia

   en.wikipedia.org/wiki/Brasso

   Brasso has also been used to polish out scratches in plastics: It has been used to polish CDs, DVDs, screens, and pools to repair scratches. It is a mild solvent and an extremely fine abrasive, so when applied to the reflective surface of the disc and rubbed radially (in straight lines between the edge and centre), it can smooth scratches and reduce their effect.

3. Polishing (metalworking) - Wikipedia

   en.wikipedia.org/wiki/Polishing_(metalworking)

   The removal of oxidization (tarnish) from metal objects is accomplished using a metal polish or tarnish remover; this is also called polishing. To prevent further unwanted oxidization, polished metal surfaces may be coated with wax, oil, or lacquer. This is of particular concern for copper alloy products such as brass and bronze. [2]

4. Surface finishing - Wikipedia

   en.wikipedia.org/wiki/Surface_finishing

   One takes great care to remove any surface defects in the metal, like pits, that could allow bacteria to grow. A #4 dairy or sanitary finish is produced by polishing with a 180–240 grit belt or wheel finish softened with 120–240 grit greaseless compound or a fine non woven abrasive belt or pad.

5. Vapor barrier - Wikipedia

   en.wikipedia.org/wiki/Vapor_barrier

   So, the use of vapor barrier should be taken into consideration. Their use has already been legislated within the building code of some countries (such as the U.S., Canada, Ireland, England, Scotland & Wales). How, where, and whether a vapor barrier (vapor diffusion retarder) should be used depends on the climate.

6. Mill finish - Wikipedia

   en.wikipedia.org/wiki/Mill_finish

   Mill finish is the surface texture (or finish) of metal after it exits a rolling mill, extrusion die, or drawing processes, including sheet, bar, plate, or structural shapes. This texture is usually rough and lacks lustre; it may have spots of oxidation or contamination with mill oil.

7. Electropolishing - Wikipedia

   en.wikipedia.org/wiki/Electropolishing

   Electropolishing, also known as electrochemical polishing, anodic polishing, or electrolytic polishing (especially in the metallography field), is an electrochemical process that removes material from a metallic workpiece, reducing the surface roughness by levelling micro-peaks and valleys, improving the surface finish.
