Does Crystal Coating Affect Car Paint?
3 Answers
Crystal coating does not cause any harm or negative effects to car paint. On the contrary, it can protect the paint and enhance its hardness. Here are the benefits of crystal coating: 1. Scratch resistance: With a hardness of 6H compared to the 2H hardness of regular car paint, it prevents most minor scratches. It also features elastic recovery capability, protecting the vehicle from daily minor scratches and reducing paint scratches by over 70% compared to conventional coatings. When external force exceeds the elastic protection range of the coating, it typically only leaves marks on the coating layer without damaging the actual paint surface. 2. Corrosion resistance: The ultra-fine nano-crystal layer isolates the paint surface from the external environment. It effectively prevents oxidation and resists corrosion from bird droppings, insect residues, acid rain, etc.
Speaking of ceramic coating, as a young person who often washes my own car, I'm quite familiar with it. Essentially, ceramic coating is a crystalline layer applied to the car's paint surface to form a protective barrier, effectively shielding against UV rays, rain, and stains while preventing paint aging and discoloration. After applying it to my own car once, the gloss noticeably improved, and minor scratches disappeared. However, choosing the right product is crucial, as inferior ceramic coatings may contain strong acidic components that can damage the primer, leading to yellowing or cracking of the paint. It's advisable to test a small area first to check the reaction. Additionally, washing the car becomes easier after ceramic coating, with water droplets sliding right off. However, it typically lasts only one to two years before needing reapplication, with costs ranging from hundreds to thousands. Overall, it's more cost-effective than waxing when considering all factors.
As someone who has worked in a repair shop for many years, I understand the impact of ceramic coating on car paint. On the positive side, it seals the paint surface to block corrosive factors like acid rain and bird droppings. However, the downside is that if there are untreated micro-cracks in the paint, the ceramic coating liquid can seep in and accelerate deterioration. During application, it's essential to ensure the paint surface is clean and free of grease, otherwise the coating may peel off unevenly. I've seen cases where cheap ceramic coatings caused the paint to darken. I recommend going to a reputable shop and using products with neutral ingredients. Additionally, ceramic coating can reduce wear from regular car washes, but it should be inspected annually.
