Why does the freshly sprayed clear coat lose its shine quickly?

[Gary]

Reasons for loss of shine are as follows: 1. Quality issues – poor quality clear coats tend to lose shine after application. 2. Concentration – high-concentration clear coats may cause a hazy appearance on the sides after spraying. The ideal technique is "thin and wet" application. 3. Technique – improper spraying can result in a hazy and uneven surface. Fullness mainly depends on the clear coat. For example, black paint may appear less deep after application and feel thin once dried, but polishing can restore a fuller look. Below is an introduction to painting and baking finishes: 1. Baking finish: Factory car paint is baked, also known as "high-temperature paint." It involves a highly complex manufacturing process and can only be applied to a bare car frame. The process includes multiple layers such as body filler, epoxy primer, mid-coat primer, base coat, and clear coat. Some premium brand paints undergo even more complex treatments to achieve optimal results, with processing temperatures exceeding 200°C. 2. Spray painting: This method involves using a spray gun or disc atomizer to disperse paint into fine droplets through pressure or centrifugal force, which are then applied to the surface. Spray painting is commonly used for basic automotive repairs.
