How Long Does a Wipe-and-Spray Coating Agent Last?
2 Answers
Automotive coating spray, applied by wiping and spraying, can last for about a year. Introduction to Coating: Automotive coating is a paint protection project that involves applying inorganic materials such as glass cellulose, silicon polymers, fluorine polymers, and high-purity water evenly on the car's paint surface. These materials form a hard, oxidation-resistant inorganic film that chemically reacts with the paint to create a glass-like protective layer. This layer shields the paint from external damage, enhances the hardness and brightness of the paint surface, and makes the car body smoother and more lustrous. Function of Coating: Automotive coating agents differ from car wax in that their molecules are smaller, allowing them to form a tighter and more durable protective layer on the car's paint surface. This layer can repel water, resist acid rain, block UV rays, and prevent the paint from oxidizing and fading.
As a car enthusiast who frequently engages in car detailing, I've personally tried several spray-on coatings, and their durability varies significantly. Generally, these products last around 3 to 6 months, but the exact duration depends on my usage. In terms of products, some big brands like Turtle Wax claim their coatings can last half a year, but the actual results often fall short. Cheaper no-name brands tend to wear off in just a few weeks. Environmental factors also play a crucial role—my car parked outside exposed to sun and rain loses its coating faster. If the car is garage-kept or I reapply the coating promptly, extending it to 4 months isn't difficult. Washing frequency has a big impact too—monthly washes can accelerate coating wear. I recommend choosing reputable brands and reapplying every quarter for better value, keeping the car shiny while offering minor scratch protection.
