Which grit level is typically used for achieving a smoother finish?

The grit level of an abrasive material refers to the size of the particles on the abrasive surface. A higher grit number indicates finer particles, which means the abrasive can produce a smoother finish on surfaces. In the context of your question, selecting a grit level that achieves a smoother finish involves understanding the purpose and effectiveness of each grit.

The 1500 grit is generally considered a fine grit, suitable for polishing applications where a smooth and reflective finish is desired. It effectively removes the finer scratches left by coarser grits while still allowing for improved surface smoothness and clarity.

In contrast, while 600 grit can prepare a surface by removing material more aggressively, it may still leave visible scratches that require finer grits for a smooth finish. The 1200 grit comes next and provides a finer finish than 600 grit but may not reach the level of polish and smoothness that 1500 grit can achieve. The 2000 grit offers an even finer finish than 1500, producing a high gloss and exceptional smoothness, but may not be the typical choice for every smoothing application, especially where slightly faster results are needed.

Selecting 1500 grit strikes a balance between refinement and efficiency for achieving a smoother finish in most general polishing scenarios.
