Choose the Right Grit Sandpapers are commonly graded as coarse (40 to 60 grit), Medium (80 to 120), Fine (150 to 180), Very Fine (220 to 240), Extra Fine (280 to 320) and Super Fine (360 and above).
Primary sanding of rough wood and the removal of planning marks on wood is often best done with medium-grit sandpaper. Fine sandpapers range from 120- to 220-grit. For most home workshops, this sandpaper will suffice for final sanding before the work is finished.

The lower the number, the coarser the grit; and the higher the number, the finer the sandpaper. Since coarse sandpaper leaves deeper scratches, start with the finest sandpaper that will tackle the project easily and work your way up to finer grits.
It is recommended to use a 320 or higher grit count to sand metal. If you need to polish metal, it is best to use a much finer sandpaper grit.

However, it is important to opt for the right grit sandpaper to remove the paint effectively and promptly. You should use 40 to 60 grit sandpaper to remove paint from wood. However, to get the paint off from edges and details, you must use finer, 80 to 120 grit sandpaper.

When you see shiny wood, it’s likely that the wood’s shine is caused by a coat of polyurethane on it. You can take virtually any piece of wood and add a DIY shiny wood finish using polyurethane. The process is not difficult but it is time consuming and takes a lot of hard work to get a smooth, flat, shiny finish.
Allow each coat to dry fully. To give the subsequent poly layers something to bond to, sand lightly between coats with 320-grit sandpaper wrapped around a hard block. Note: The first coat needs the most sanding to appear smooth; don’t worry if it doesn’t look as flawless as you’d like at first.
