What is the best finish for plastic?
Most plastics are manufactured with a very good surface finish. Iron and Steel – mild steel, tool steels. Steels rust (except stainless steel) so they need to be protected against moisture and air. Coating in oil or grease is effective as long as the coating is not removed.

What are the advantages of ABS plastic?
ABS has a low melting point, which enables its easy use in the injection moulding process and 3D printing. It also has high tensile strength and is very resistant to physical impacts and chemical corrosion, which allow the finished plastic to withstand heavy use and adverse environmental conditions.
What are plastics finishes and how are they used?
