Car polishing should typically be done two to three times a year, depending on various factors such as driving conditions, exposure to the elements, and the type of polish used. If a car is frequently exposed to harsh weather, road salt, or excessive sunlight, more frequent polishing—every three to four months—may be necessary to maintain the paint’s shine and protection. Light polishing can be done quarterly to enhance gloss, while medium polishing, which removes minor scratches and swirl marks, is best performed every six months. Heavy polishing, involving a cutting compound for deeper scratches, should be limited to once a year to prevent excessive wear on the clear coat. Over-polishing can thin out the protective layer of the paint, so it’s important to strike the right balance and always follow up with waxing or sealing for long-term protection.
