Curved surface polishing is one of the more challenging processes in fine sanding. The streamlined curves of automotive paintwork, the complex surfaces of model figures, and the rounded edges of furniture all face the same problem: how can high-grit sandpaper conform closely to curved surfaces without excessive cutting or damaging the original shape?

Many operators believe that since they look similar, using them interchangeably won’t cause any major issues. However, in reality, these two types of sandpaper belts differ completely in terms of base material, adhesive, and abrasive grain arrangement. Using the wrong one is not just a matter of wasting the belt—the real cost lies in scratched workpieces and damaged equipment. Therefore, understanding the differences between them is the first step in avoiding these problems.

In automotive bodywork and painting, as well as mechanical sanding operations, if the pneumatic sandpaper used with pneumatic sanders loses grit or sheds backing, it not only affects surface quality but also reduces work efficiency. Identifying the underlying causes is a crucial step toward improving these conditions. Below, the DMS editorial team provides an analysis of the causes.

In machining and surface finishing, the correct selection of sandpaper type, grit size, and grinding process directly impacts workpiece quality and production efficiency. Below, the DMS editorial team provides selection recommendations for four common materials—wood, metal, plastic, and fiberglass—to help you better understand machine-use sandpaper.

Many car owners may not know what grit to start with when using wet sandpaper for paint restoration, scratch removal, or fixing orange peel texture. If the grit is too coarse, it can easily sand through the clear coat and damage the original paint. if it’s too fine, it won’t remove the imperfections, resulting in a waste of time and materials. Below, the DMS editorial team will explain the correct starting grit and sanding sequence for different paint issues.

While dry-grit and wet sandpaper may appear similar, they actually have distinct characteristics. Choosing the wrong type can directly negatively impact grinding results, workpiece surface quality, and overall production efficiency. How do you make the right choice? The DMS team is here to help.
