When it comes to sanding, scratches are often an unwanted result that can ruin the surface you are working on. While there is no such thing as sandpaper that doesn't scratch, some grits are less likely to leave noticeable scratches than others. Here is what you need to know about sandpaper grits and scratches:
The grit of sandpaper refers to the number of abrasive particles per square inch on the paper. The higher the grit number, the finer the abrasive particles, which means that higher grits remove less material and leave a smoother finish. However, as the grit gets higher, the abrasive particles become smaller, which means they can't remove larger imperfections.
So, while higher grits can make the surface smoother, they won't remove deep scratches or rough spots. In fact, using high grit sandpaper on a rough surface can actually create more scratches because the finer grit particles can get stuck in the deeper scratches and cause them to widen.

One solution to this problem is to use a combination of sandpaper grits, starting with a coarser grit and working your way up to a finer grit. This way, you can remove any large scratches or imperfections with the coarser grit and then smooth out the surface with the finer grits.
Another option is to use sanding pads or sponges, which have a softer, more flexible abrasive surface than sandpaper. These can conform to the shape of the surface you are sanding and are less likely to leave noticeable scratches.
In summary, there is no sandpaper grit that won't scratch at all, but using the right grit for the job and combining grits can minimize the appearance of scratches and give you a smoother finish. It's also important to use the proper technique and apply even pressure when sanding to avoid creating unnecessary scratches.
