How does paint protect metal and what happens to the paint cracks?

The paint forms a seal and prevents water and air from reaching the metal surface and prevents corrosion or rust from forming. A crack in the paint would allow water to reach the metal and cause corrosion or rusting beneath the paint surface, out of sight until the rust becomes visible. A road chip thrown against a car's paintwork is a likely cause of pitting on a car - which spreads and causes rust holes in the car's bodywork unless treated as soon as possible.
