Generally, the bumper is removed for a full repaint, but for small-area touch-ups, it can be painted without removal. As for whether the paint matches the original factory parameters, it depends on whether the repair paint brand used by the 4S shop is consistent with the factory paint. Usually, manufacturers provide 4S shops with several brand options, along with corresponding color paint formulas, to ensure accurate color matching. Waxing: Waxing can be done directly or after polishing. Direct waxing involves cleaning the car body and applying wax directly to the top clear coat layer. Polishing waxing, on the other hand, requires using a polishing machine to polish the paint surface before applying wax, which can instantly make the car shine. Glazing: Due to the composition of the glaze, it is not resistant to acid or alkaline cleaning and is easily damaged. It typically lasts only 1 to 3 months. Additionally, glazing can harm the car's paint, requiring reapplication every two to three months. Crystal Coating: Crystal coating is a hard protective layer specifically designed for car paint surfaces, seats, interior and exterior trim, glass, tires, and other key areas. It comes in fast-drying and slow-drying types, primarily determined by the main ingredients. Film Application: Car coating is a high-level protective measure that enhances paint shine while offering multiple benefits, including resistance to acids and alkalis, high-temperature tolerance, strong waterproofing, oxidation resistance, and UV protection.
