What harm does coating agent do to cars?
2 Answers
Coating agents can harm cars in the following ways: Harm 1: The coating agent chemically reacts and integrates with the car paint, penetrating into the paint layer and filling the gaps between paint molecules, thereby damaging the original molecular structure of the paint. Harm 2: The coating has a short duration. Harm 3: It can reduce the thickness of the car paint to some extent, causing damage to the paint. More information: Car coating is a paint protection service that involves applying an inorganic film of high hardness and oxidation resistance uniformly on the car paint surface using environmentally friendly materials such as glass cellulose, silicon polymers, fluorine polymers, and high-purity water. Through a chemical reaction with the car paint, it forms a glass-like protective layer that shields the paint from external damage while enhancing its hardness and gloss.
I've used many coating agents, and honestly, inferior products can really damage the car paint. Some cheap formulas contain strong acidic ingredients that make the car shine initially, but gradually corrode the paint surface, especially on dark-colored cars where white patches appear first. Last time I helped a friend with his car, after the coating agent dried, it stuck to dust like glue. When washing, we found dust particles embedded in the hardened film, and scrubbing hard directly scratched the paint. DIY application is even more troublesome; unevenly wiped areas leave streak-like water marks that become impossible to remove over time. Now, I always recommend choosing water-based products from reputable brands. They might be more expensive, but at least they won't damage the paint.
