Exposed primer will rust if it rains, but not immediately. The rusting of iron is a very slow chemical reaction. As long as you wipe off the water and apply paint, it won't rust. If you don't apply paint for a long time, even without rain, the moisture in the air will gradually cause the iron to rust. Below is relevant information about car paint: Introduction 1: Automotive paint has undergone three major leaps in history - alkyd (enamel) paint in the 1920s, acrylic (enamel) paint in the 1960s, and clear coat (urethane) in the 1980s.
