We received this Kia this week that was left in an underground parking garage for an extended period. Water had dripped on the car through cracks in the concrete structure and deposited THICK layers of the minerals it picked up from the concrete. Obviously this wasn’t just potentially harmful to the paint but also looked terrible. We carefully removed the mineral deposits and then polished the car, followed by a fresh coat of paint sealant for protection to restore the paint to it’s prior condition.
