The flap discs of your angle grinder are used for a polishing flat surface for finishing work. The discs are made with different grains that vary from material to material.

In general the more material you want to remove the more power the disc should have. The grinder leaves a clean but not the smooth surface.

Sandpaper pads or flapper wheels are used to smooth out any surface. They are designed for a cleaned and finished look. They are also used for rounding the edges and curved angles rather than the sharp ones.

The polishing is done by the same method but soft cotton wheels are used instead of fine abrasive emery and sandpaper in smoothing.

Smoothing and Polishing is a very time taking process but it’s more rewarding.
