How to Make Pitted Metal Smooth | eHow

Pitted metal is caused by rust eating down below the surface of the metal. It causes an uneven surface that must be smoothed out before it can be used or painted. It's vital to remove all the rust when working with the metal or the problem will simply return. Once the metal is smooth, it needs to be protected to prevent further oxidization.

Grinding is often a final machining step to achieve desired surface finish or final dimensions. Grinding is a high-energy process where a lot of frictional energy is concentrated over a small region [1]. This localized energy is confined to the surface layers of the part being ground, resulting in a local rise in the surface temperature.
