Does Coating Liquid Damage the Car?
3 Answers
Coating liquid can damage the car. Reduces the thickness of the car paint: The coating agent chemically bonds with the car paint, which can cause some damage. Before applying the coating, the car paint needs to be polished, and polishing itself is harmful to the paint as it reduces its thickness. Additionally, the coating agent chemically fills the gaps between the paint molecules, which can disrupt the original molecular structure of the paint. Short duration of effectiveness: The coating agent's effects are short-lived, requiring multiple applications. Each application necessitates polishing the car paint again, which gradually makes the paint thinner. Thinner paint makes the car more susceptible to scratches.
I've been driving for over five years and have used coating solutions several times. Honestly, they don't cause much damage to the car as long as you use them correctly. However, the first time I tried it, I bought a cheap, no-name brand and applied it to a car body that wasn't completely dry. As a result, water stains seeped into the paint, and I had to spend money on polishing to fix it. Since then, I've only chosen products from reputable brands like 3M or Turtle Wax, making sure the car is thoroughly washed and dried before application, and I apply it in a shady, wind-free area. Coating solutions can form a protective layer that shields against acid rain and UV rays from the sun, reducing paint aging and oxidation. However, applying too many layers or reapplying too frequently can lead to residue buildup, clogging the paint's micro-pores. I recommend applying it once a year—that's enough. Beginners should avoid DIY failures and opt for professional application for peace of mind. In short, when used properly, it's a great tool for car maintenance.
As someone frequently involved in vehicle maintenance, whether coating liquid damages car paint primarily depends on product quality and application procedures. High-quality coating liquids contain protective resin components that resist dirt and scratches, but inferior products may include corrosive additives that cause micro-cracks after adhesion. I've witnessed lessons from DIY mistakes by car owners: applying coating without thorough surface cleaning or in dusty conditions leads to fine scratches or water spots; in high-temperature environments, the coating dries too quickly, making uniform application difficult and prone to bubbling. The correct procedure involves first removing old wax with a polishing disc, then applying a thin layer of coating liquid—don't overlook ventilation. This extends paint lifespan and prevents environmental contaminants from eroding the surface. I recommend regularly inspecting the coating's condition and promptly repairing minor flaws to prevent deterioration.
