Sand through the grits.

The simulator lets you practice a sanding sequence before you put paper to a real surface. Choose a material, start with the right grit, and work through the scratches until the finish is ready for the next step.

It is a visual lesson, not a substitute for checking the surface as you work. For the practical version, use the sandpaper grit chart, then see the recommended sequences for woodworking and auto body work.
